Ancillary Market Mechanism for Load Participation in Peak Load Shifting of Power System with High Penetration of Renewable Energy

Abstract

In the new power system with higher penetration of renewable energy, the peak-to-valley difference of net load increases, and due to the limited regulation capacity of the power generation side, it is necessary to introduce loads to participate in peak regulation. A reasonable incentive mechanism is needed to increase the enthusiasm of load participation in regulation. In this paper, we propose an ancillary market mechanism for loads to participate in peak load shifting. The transaction framework is designed, where load incentives are provided jointly by power grid companies and renewable energy power generation enterprises; the trading model and method are introduced, including the calculation method of dynamic electricity price difference; and the implementation process is formed. Finally, the feasibility of this mechanism is verified by a numerical example.
