1.   Development of community energy service market and management platform

지원 : 한국산업기술진흥원
기간 : 2018. 10. 01 ~ 2020. 09. 30 ( 2 years )
참여기관 : Power21, 아주대학교

- Development operation algorithm of EMS
The operation algorithm of EMS is divided into Load Agg, REG Agg and ESS Agg by type of target resources. Because the overall objective of EMS operation is participation into energy market, basic objective function of each EMS is enhancement of profit for both EMS operator and resource owner.

- Development interoperability technology of each EMS
Develop interoperability technology between each EMS to operate more efficient EMS and maximize profit. Interoperable technology can increase economic value when participating in trading platform. For this, analyze the available operation scheme for each configuration such as Load – ESS or REG – ESS. Judgment on whether each configuration is possible follows the economic value and the rules of the current electricity market. Finally, we derive the interconnection plan and calculate expected profit according to each combination.

기간 : 2017. 05 ~ 2020. 04 (3 years)

참여기관 : 아주대학교

The presence of High Impact Low Probability (HILP) disaster is a serious threat to the power system. The ability of the system to recover into its original condition is vital to the power system. The Grid Resilience Improvement Algorithm (GRIA) developed will try to make the system returns as close as possible to its original condition before the HILP event strikes the system. The algorithm will consider some these actions:

  • Develop power system damage forecasting
  • Develop power system hardening
  • Develop the optimal location of DER and loop line to reduce the restoration time
  • Develop the power system reconfiguration algorithm

The result of this will be used to improve the system ability to withstand the same type of HILP event
