Optimal planning method of renewable distributed generation for multiple prosumers participating in distribution networks

In the situation that distribution system operator (DSO) and multiple prosumers jointly invest distributed generation (DG) in the distribution network, it is difficult to achieve the balance of multi-agents interests under the requirements of security operation and privacy protection. To solve this problem, an optimal planning method of DG for multiple prosumers participating in distribution networks is proposed. First, the DG planning model of DSO and prosumers are constructed separately, and the network tariff dynamic updating strategy is proposed for the optimal guidance of multi-agent collaborative planning. Then, based on the collaborative planning framework for distributed autonomous decision-making of prosumers and the global coordination of DSO, a distributed solution method is proposed. Finally, the effectiveness of the proposed method is proved through the simulation results, the experiment proves that the network tariff updating strategy can better guide the multi-agent DG collaborative planning, and has better effects in balancing the benefit of prosumers and DSO.
