Study on the Evaluation Method of New Energy Carrying Capacity of Distribution Network Considering Flexible Load Response

An evaluation method of new energy carrying capacity of distribution network is proposed. Firstly, an evaluation model of adjustable characteristics of demand side response(DSM) of air conditioning load in distribution network considering cluster aggregation effect is established. Then the response model of electric vehicle is established by Monte Carlo simulation method. On this basis, a network reconfiguration model(NRM) suitable for evaluating the new energy carrying capacity of distribution network is constructed. Then, aiming at the maximum access capacity of distributed new energy, an evaluation model of new energy carrying capacity of power grid taking DSM and NRM is established. Finally, the simulation example uses the improved IEEE 33-node distribution network to evaluate the new energy carrying capacity of the system in different scenarios. The analysis results show that DSM and NRM can effectively improve the carrying capacity of distributed new energy in distribution network.
