Study on Operation in Power System Utilizing Customer's Resource for Providing Demand and Supply Regulation

Higher penetration of renewable energy (RE) generations in power system makes more difficult to keep demand and supply balancing due to augmentation of volatility in RE's generation output. To solve this problem, the authors focus on regulation capacity procurement from consumer's resources. However, utilizing customer's resource must be considered uncertainty of regulation caused by demand variation due to owner's convenience. Moreover, it is necessary to consider voltage fluctuation by regulation in distribution system where many resources are integrated. Therefore, this paper proposes novel operation method utilizing customer's resource with active power regulation and reactive power compensation for providing demand and supply considering uncertainty of owners' convenience and voltage influence on distribution system.
