Benefits Allocation Method for Demand Response in Smart Distribution Network with High PV Penetration

Under the background of the Chinese government has committed that China will achieve peak carbon dioxide emissions before 2030 and carbon neutrality before 2060, renewable energy and distributed generation (DG) have once again focused people’s attention. However, the access of DG will cause the reverse power flow of the distribution network, which will cause problems such as voltage overruns and voltage fluctuations. To a certain extent, these problems can be solved by demand response (DR). This paper proposes a DR benefit allocating method in smart distribution network (SDN) with high PV penetration, which constructs a user’s demand response contribution (DRC) index system, and uses the TOPSIS ranking method to comprehensively evaluate the user’s DRC. The calculation example proves that the proposed index system can more comprehensively measure the DRC of users, and can provide a fairer apportionment index for the next benefit allocation, compared with the traditional method of benefit allocation based only on the amount of interactive electricity in DR.
