Project Title: Open Microgrid Project
Organization: Korea Electric Power Corporation
Country: Republic of Korea
Website: http://home.kepco.co.kr/kepco/EN/main.do

The ‘Open Microgrid Project of Korea Electric Power Corporation (KEPCO)’ covers the construction and demonstration of two types of microgrids designed and operated by KEPCO: a consumer community-based independent microgrid (MG) and a grid-connected microgrid, involving different types of distributed energy resources such as renewable energy, ESS and etc. The project stemmed from KEPCO’s recognition of the importance of microgrid (MG) technology that can ensure reliability and resilience in energy supply while contributing to resolving energy production and consumption problems.

The main goal of the project was to build and test-operate optimally designed microgrids that can alleviate voltage variations and electricity quality issues deriving from intermittent renewable energy production as well as increasing distributed energy production in the grid following the Korean government’s ambitious plan to expand the renewable energy ratio to 20% of the energy mix by 2030, reaching 63.8GW in total installed capacity. Once completed, the project was expected to resolve the imbalance between power supply and consumption, maximize energy efficiency, increase electricity quality, ensure resilience, and to quickly respond to abrupt changes in the power grid and systems.

For the project KEPCO developed distinctive engineering technologies for power source design, capacity design and power system structural design to maintain renewable energy supply at a 100% level. In October 2014, after extensive evaluation, KEPCO selected Gasa Island in Jindo-gun, Jeollanam-do, located in the southern part of Korea, as its pilot location. Through the demonstration operation of a year-long project, KEPCO managed to successfully prove the possibility of reliable power supply, as well as power generation control, ESS control and load control. The project showed more than 50% reduction in operating costs, improved power quality and lower fuel costs, resulting in economic savings of approximately USD 3.7 million per year.

In addition, KEPCO built and test operated an active distribution grid (“utility MG”) that combined a next generation distribution automation system with a grid-connected microgrid. This was to improve grid efficiency as well as the utilization rate of renewable energy. The pilot sites selected were grid-connected islands in Anjwa-myeon, Bigeum-myeon and Palgeum-myeon, where a distribution operation center and three grid-connected microgrids were established. KEPCO demonstrated its active distribution operation technology (voltage control, microgrid-based independent operation in case of emergency, active and reactive power control, etc.) and proved the feasibility of microgrid as energy resource and the increased utilization rate of renewable energy. Using these results and technologies, KEPCO demonstrated its active microgrid system with Alectra Utilities, which supplies power to the northern part of Toronto and central Ontario, Canada, between January 2016 and December 2017 at Penetanguishene. Through this long-term demonstration project, KEPCO earned a successful track record in the operating environment of the North American power distribution business, which is expected to further boost overseas exports including the North American market.

The core technologies acquired through this project, such as engineering, operating system, and operational performance, have already played a role in triggering the energy-independent microgrid project developments on domestic islands (Deokjeok Island, Ulleung Island, etc.). Furthermore such endeavor has helped laying the foundation for developing and enlarging overseas markets such as Africa, Canada and Southeast Asia. The expansion of these businesses is expected to bring economic and social benefits by creating ecosystem of microgrid related industries and new job opportunities.

Integrated planning of renewable energy sources and flexible consumers incorporating technical, market and social factors presents major challenges to the establishment of a regional smart grid concept. The aim of the project ‘Rural Intelligent Grid’ was to develop and test a novel interactive energy and infrastructure design tool for the pro-integrative optimal planning and operation of new emerging energy infrastructures in rural areas. Following the motto of the ERA-Net Smart Grids Plus Initiative “from Local Trials towards a European Knowledge Community” RIGRID was implemented and demonstrated in rural regions in Poland and Germany. The project addresses all three research layers of the initiative such as technology, stakeholder and marketplace. The technical modules of RIGRID-tool include computer programs serving for the planning of optimal structures of newly designed AC low voltage microgrids finding the best corridors for power lines or cables and choosing the optimal site for installing distributed generation sources (DGS), renewable energy sources (RES) and battery storage systems. The optimal operation of microgrid is realized within newly designed EMACS (Energy Management and Control System), which can monitor and control any processes related to generation, storage and use of energy from RES sources, as well as obtain data that will be used for business analysis. The RIGRID virtual reality based design tool is used for interactive planning of infrastructure and testing various technical variants of the planned microgrid configuration. Thus the acceptance of the local community and groups of interest can be analyzed, which brings the discussion between stakeholders, local authorities and inhabitants to the level of facts, eliminates concerns, overcomes the socio-economic barriers and accelerates the decision-making process and implementation of planed investments.

Project Title: City Of Summerside Mypowernet
Organization: City Of Summerside
Country: Canada
Website: www.city.summerside.pe.ca

The MyPowerNet project is the creation of an electrical information network that connects consumer loads to the needs of the electrical grid while taking into account the environmental needs of incorporating more renewable energy sources to the electric energy portfolio of the utility. By creating a smart network of control, consumer loads can be coordinated with the variability of the renewable electricity sources of wind and solar.  By controlling when the electricity is given to the consumer, without sacrificing the consumers services or lifestyle, the infrastructure of a smart grid can be beneficial to the three main stakeholders, those being the electric utility, the consumer and the environment.  For 8 years the City of Summerside has been expanding its smart grid to show that the utility can benefit, the consumer can benefit and the carbon footprint of the community can be reduced.  By allowing the electric utility to choose when the electricity is needed, the utility can now use the smart grid to shape its load curve to match its grid electricity sources which creates a more stable, reliable and resilient electricity grid while achieving the highest possible percentage of renewable energy that is highly variable.
