| Summary: | With the development of household photovoltaic and electric vehicles, household electricity units are no longer traditional power consumers, but also power producers, which are defined as Prosumers. In order to solve the problems of Prosumer energy circulation and its grid-connected control, this paper proposes a new Prosumer energy management method. First, PSO algorithm is used for day-ahead optimization to smooth the load curve of prosumer. Then based on the Smart Load (SL) which can control the active power flexibly, the real-time energy management method of Prosumer is proposed. At last, the multi-Prosumers grid-connected hierarchical control strategy is established combined with tree-shaped and ring-shaped agent technology. Not only can it improve the utilization rate of household photovoltaics, but also it can reduce the adverse effects of photovoltaic and EV large-scale grid-connected in the traditional way. On the basis of participating in the load regulation of the distribution network, Prosumer can improve the stability of its power consumption.
