Design on Virtual Power Plant Participating in Ancillary Service Market and Research on Internal Benefit Allocation Mechanism

Under the carbon peaking and carbon neutrality goals, the high proportion of fluctuating and intermittent renewable energy is accessed to the power grid, which brings severe challenges to the safe and stable operation of the power system. Virtual power plant (VPP), as an effective means of large-scale and normal dispatching of distributed resources (DRS), provides a new way to solve this problem. However, at present, the design of ancillary service trading varieties of VPP, the construction of market environment, and the allocation of internal benefits among DRS are far from mature. In this paper, the ancillary service market mechanism of VPP and benefit allocation method are proposed. Firstly, the ancillary service market mechanism of VPP is designed to provide ancillary services including peak-regulation service, frequency-regulation service, reservation service, and reactive power service. Secondly, the benefit allocation method among DRS is designed so as to fully arouse the enthusiasm of DRS to participate in VPP. Finally, a case is given to verify the validity of the proposed benefit allocation method which can fully guarantee the comprehensive contributions of DRS. It provides ideas and references for VPPs to participate in ancillary service market transaction and benefit allocation.
