Energy systems around the world are undergoing a paradigm shift, driven by the need for decarbonization and the rapid growth of decentralized, variable renewable energy sources. A key element for the effective integration of renewable and decentralized energy sources into the power system is the use of flexibility from distributed resources, e.g., for market participation or the provision of grid services.
As part of the IEA TCP for a Co-operative Programme on Smart Grids (ISGAN) Working Group 9,
we access insights from existing European and non-European power systems, markets, and
pilots to understand the issues and implications of flexibility market design.
The main barriers for using distributed flexibility can be grouped into three sub-categories:
• technical barriers • consumer engagement • regulatory barriers

The global energy landscape is in the midst of a profound shift towards flexibility markets and distributed solutions, necessitating a nuanced understanding of their impact on operational planning. This research, conducted under the International Smart Grid Action Network's Working Group 9, delves into the intricacies of flexibility within the Austrian, Canadian, and Korean electricity systems. Leveraging prior research, the collaborative effort sets the stage for a comprehensive exploration of flexibility markets across diverse regions.
Employing a multi-faceted methodology, the work was initiated with a thorough review of electricity systems in the participating countries. Based on this review, a targeted stakeholder questionnaire, complemented by in-depth interviews with system operators, aggregators, and consumer associations, facilitated not only insights extraction but also a comparative synthesis of stakeholder views.
It can be acknowledged that barriers to distributed flexibility use range from technical constraints to regulatory hurdles, highlighting the absence of a comprehensive regulatory framework. Smart meters, while ubiquitous, still face technical challenges and regulatory barriers impede Distribution System Operators (DSOs) from accessing flexibility resources, necessitating further clarification.
Globally, a consensus emerges on the imperative for refined regulatory frameworks and clarified roles. Challenges persist in technology and infrastructure for measurement and verification, hindering seamless flexibility integration. It could be demonstrated that flexibility potential as a network reinforcement tool faces unpredictability, mitigated by advancements in predictability and regulatory evolution. European perspectives underscore grid topology’s significance in leveraging local flexibilities.
Distinct business models surface across regions, with Austrian Flexibility Service Providers focusing on ancillary services, short-term markets, and Virtual Power Plant (VPP) solutions. Persistent customer engagement challenges highlight the need for education and financial incentives.
In conclusion, the diverse designs of global electricity markets necessitate tailored approaches for the successful implementation of flexibility markets in operational planning. Regulatory clarity and continuous stakeholder engagement emerge as pivotal factors in navigating this evolving energy landscape.

The ReFlex Guidebook for the replication of use-cases tackling the flexibility challenge in smart energy systems is based on the ReFlex project, which aimed to develop a replicability guideline for the deployment of technologically feasible, market-based and user-friendly solutions for smart grids with a high level of flexibility. The focus was put on grids with an expectedly high level of renewable energy production which is effectively and efficiently used locally through mixes of measures from voltage regulation, demand response, energy management and storage. in eight demo sites in Austria (AT), Germany (DE), Sweden (SE) and Switzerland (CH). Four of them – Salzburg-Köstendorf (AT), Island of Gotland (SE) and Malmö-Hyllie (SE), Lausanne-Rolle (CH) – involved demo sites situated in larger areas with a distribution system operator (DSO) as the main project partner. The other four of them – Biel-Benken (CH), Güssing (AT), Hartberg (AT) and Wüstenrot (DE) – are situated in smaller areas with less than 15,000 inhabitants involving private and public owned energy utilities, which did not have to unbundle grid operation from energy supply.
