Webinar – Demonstration of grid forming capabilities and synchronisation services

05 April 2022 - 13:00 CEST - ISGAN Virtual Learning and the OSMOSE project invite you to this webinar concerning off-the-shelf inverters interfacing energy storage systems.

The speakers will lead you towards two demonstration activities part of the OSMOSE project concerning off-the-shelf inverters interfacing energy storage systems with the power grid that can be turned into grid-forming units through suitable control upgrades in order to provide several services to the power system when it hosts massive amount of inverter-based renewable/stochastic generation. This is achieved thanks to the provision of synchronisation services superposed to classic regulation ones.


Join the webinar: 2022-04-05 at h 13:00 CEST (UTC+1)

Key messages

Within the context of service provision to future power systems hosting massive amount of inverter-based renewable/stochastic generation, 2 demonstrators have shown that grid forming capability can be provided from off-the-shelf equipment. One demonstration is based on a existing MW-class BESS connected to the medium voltage grid of the EPFL campus, while the other was built for the OSMOSE project by Ingeteam and connecter to the RTE network.

  • Both demos proved that grid forming capability can be provided without hardware oversizing, drawing out the most of existing equipment and therefore limiting the cost.
  • A hybrid system showed that supercapacitors installed on the DC side can handled all fast transients induced by grid forming control, therefore smoothing the battery output power.
  • The controls have been improved to behave properly in different grid conditions including harmonics and unbalanced conditions.
  • Multiservices provision can be done including grid forming capability taking into account the unit’s operational constraints.
  • Accurate distribution-class PMUs can be used to assess the performance of grid forming vs grid following units.

Intended audience

This webinar is mainly suitable for transmission system operators (TSO), energy providers, converter manufacturers and researchers in the field of power electronics and/or power systems stability and control. The content of the webinar is also comprehensible for students and engineers with some background in the power systems dynamics.

Webinar – Dynamic Virtual Power Plant to combine flexibilities of dispatchable and non-dispatchable RES – the POSYTYF project

18 November 2021 - 15:00 CET - ISGAN Academy Webinars invites you to discover the Dynamic Virtual Power Plant (DVPP) concept under development by the POSYTYF project.

This webinar introduces the Dynamic Virtual Power Plant (DVPP) concept under development by the European Commission funded project POSYTYF, that aims to facilitate Renewable Energy Sources (RES) integration into the electrical network. After an overall project presentation, the webinar will introduce the proposed DVPP concept and detail the first project deliverable: the definition and specification of DVPP scenarios.

More info on https://posytyf-h2020.eu/

Join the webinar: 2021-11-18 at h 15:00 CET (UTC+1)

Key messages

  1. The new DVPP concept fully integrates the dynamic aspects at all levels: locally (for each RES generator), globally (for grid ancillary services and interaction with other neighbour elements of the grid) and economically (for internal optimal dispatch and participation to electricity markets)
  2. A DVPP is a set of Renewable Energy Sources (RES) along with a set of control and operation procedures. This means methodologies for:
    • choosing the participating RES, optimal and continuous operation as a whole (especially in case of loss of natural resources – e.g., wind, sun – on a part of the DVPP),
    • regulation (in the dynamic sense) to ensure local objectives for each generator,
    • participation to ancillary services of the DVPP as a unit and to diminish negative effects of interaction with neighbour dynamics elements of the power system,
    • integration in both actual power systems scenarios (with mixed classic and power electronics-based generation) and future ones with high degree of RES penetration.

Intended audience

  • Power system engineers, from students to senior experts.

micro vs MEGA trends

micro vs MEGA: trends influencing the development of the power system

micro and MEGA represent two trends which largely influence the decisions and the evolutionary process of power grids.

The trends are both aimed at enabling very high penetration of renewable energy sources
in the electric power system, from two perspectives:

  • micro focuses on local solutions, while
  • MEGA focuses on system or even intra-system wide solutions

ISGAN Annex 6 has dedicated an activity to study the micro and the MEGA trends, with the objective to present a critical assessment of these trends, based on the questions:

  • Does one trend outcompete the other?
  • Does increased investments from one perspective increase the need for investments
    from the other perspective?
  • To what extent can one perspective benefit from the other perspective?

The intention is not to proclaim one solution being superior to another, rather to provide well
informed insights to the needs of considering both perspectives during the planning
and decision-making process for the sustainable development of the wider energy

The outcome of this activity are communicated through publications, presentations and workshops, with contributions from a large number of parties:



  • Workshop and meeting in Montreux
    A highly successful event, gathering a total of 30 participants, with presentations (available here) from Italy, India, Spain, Belgium, France, Germany, Norway and Sweden.
    The participants at these two meeting days have shown a high level of engagement and it has been highly valuable to learn from each other. In short, we can conclude that these meetings were very productive and successful in gathering a large amount of knowledge.

Webinar: The need to model coupled energy networks to transition to a decarbonized future

The coordination between planners and operators of coupled energy systems will allow the further integration of renewable energy sources in the electricity network by storing energy in fuel form over long periods of time using power-to-gas, the recovery and more efficient use of heat, and the decarbonization of industrial processes and transportation modes that can’t be electrified. Energy networks, such as electricity grids and natural gas pipeline networks, have traditionally been planned and operated independently. In order to enhance the integration and coordination of different energy networks, they must be planned and operated in coupled ways. Different energy networks have historically been and are still modelled by different tools.

27 Feb 2020 @ 14:00 CET

Duration: 1h

In this webinar it will discuss the need to model coupled energy systems in a single framework and we will introduce encoord’s Scenario Analysis Interface for Energy Systems (SAInt), a software application to model, plan, and operate coupled energy networks.

Why the TSO-DSO Relationship Needs to Evolve

A number of emerging trends indicate that the interaction between transmission system operators (TSO) and distribution network operators (DSO) will evolve in the coming years.

Examples of these trends are the electrification of energy consumption and the increasing volume of distributed generation being connected to the distribution grid.

The relationship between transmission system operators (TSO) and distribution network operators (DSO) is changing. Examples of these trends are the electrification of energy consumption and the increasing volume of distributed generation being connected to the distribution grid. In Europe this subject is highly relevant as pointed out by ENSTO-E (European Network of Transmission System Operators for Electricity) in their paper, Towards smarter grids: Developing TSO and DSO roles and interactions for the benefit of consumers published in March 2015, and ACER (Agency for the Cooperation of Energy Regulators) in their conclusions paper, Energy Regulation: A Bridge to 2025 published in September 2014. ENTSO-E is an association which represents 41 European TSOs and has an objective to promote closer cooperation across Europe’s TSOs to support the implementation of EU energy policy objectives of affordability, sustainability and security of supply. ACER is an agency of the European Union with the overall mission to complement and coordinate the work of national energy regulators at EU level, and to work towards the completion of the single EU energy market for electricity and natural gas. The expected increased interaction between TSOs and DSOs will result in both technical and non-technical challenges.

IEA ISGAN Annex 6 has published a discussion paper in which the current and future cooperation between TSOs and DSOs has been investigated. Six critical grid operation challenges have been identified:
1. Congestion of the transmission-distribution interface
2. Congestion of transmission lines and distribution lines
3. Voltage support (TSO↔DSO)
4. Balancing challenge
5. (Anti-)Islanding, re-synchronization, and black-start
6. Coordinated protection

For each case, country experts provided first-hand information about the status and expected development of TSO-DSO interaction in their respective countries. This resulted in an overview, by country, of the interaction between grid operators and provided input for the discussion about how this interaction could evolve in years to come. Technical aspects, as well as policy aspects, have been taken into account.
The technical solutions required for a closer interaction between TSOs and DSOs are very similar for most of the identified cases, except for the case of islanding & black-start. From a high level viewpoint, grid monitoring has to be implemented, communication between TSO and DSO has to be established and means of communication between the DSO and its flexible customers have to be available. DSOs should also be able to perform (quasi) real time network simulations with input from measurements on the grid.
Such technical requirements should not be underestimated regarding implementation and operational cost, complexity and skills required. These could be a challenge, especially for smaller distribution network operators. Nonetheless, only the distribution grid operator has information about the actual grid configuration and grid loading. This means that even when other entities take up certain roles, for example the role of aggregator, the distribution network operator will always be responsible for monitoring the grid and will need to implement communication solutions to one entity or another.
With the current status of technology, technical requirements for an evolved interaction between TSOs and DSOs can be met. However, several non-technical issues, or points of discussion, have been identified which are closely related to the regulated environment grid operators are working in.

• Maintaining a balance between infrastructure investments and use of flexibility

Flexible demand and generation can be used to support grid operation and avoid infrastructure investments. A minimum use of flexibility will be necessary to avoid over investing, but the impact on the processes and business cases of flexible customers has to be limited. The flexibility available by curtailing renewable energy sources needs to be limited to avoid a high loss of renewable energy.

• The role of markets
Which grid operation challenges should be met by introducing markets and which should be managed only by technical means and appropriate bilateral contracts? It is proposed to use market mechanisms only for the balancing challenge, which is applied today in various countries. Coping with local grid operation challenges such as critical transformer loading, line loading and voltages, is proposed to be managed by the network operators, optimally interacting with each other and using flexible customers when necessary. Because of the local nature of the mentioned grid operation challenges, markets would not work efficiently. Instead, a regulatory framework is required for bilateral contracts between flexible customers and network operators, facilitating the use of flexible generation and demand for grid operation purposes.


• Setting a level playing field for flexibility
When the combined flexibility of customers on the distribution and transmission grid is used, favoring one set of customers at the cost of the other should be avoided. For example, when facing critical line loading on the transmission grid, the use of flexibility of only distribution connected customers would be undesirable. Some mechanism, probably in discussion with the regulator, should be implemented to cope with this.

• The role of regulation
Closely related to the previous statement is the discussion point on how grid operation should evolve:
more regulated, with clearer and stricter roles, or more open, with guaranteed interaction between grid operators and new market players? There is no one size fits all solution but in any case, a clear definition of the roles and responsibilities of all participants in future grid operation will be necessary and will serve as a good start.
A clear policy framework will, in every case, push forward investments in Smart Grid solutions to deal with the discussed challenges that grid operators are facing.
The article is based on a discussion paper published by IEA ISGAN Annex 6.
