Cooperative Demand-Side Local Energy Trading among PV Prosumers in Distribution Systems Considering Voltage Regulation

In this article, we propose a P2P based distributed dual loop energy management method with voltage regulation capability. In the inner loop process, various prosumers engage in P2P multilateral negotiation and iteration through energy sharing cooperation without considering the physical constraints of the distribution network to achieve the optimal energy trading. Then, the distribution network operator (DNO) calculates the node voltage of the distribution network in the outer ring, updates the price of energy interaction between prosumers and the superior power grid, and guides over/under voltage producers to make decision changes to maintain the voltage security of the distribution network. In addition, we use the alternating direction method of multipliers (ADMM) to update the electricity consumption decisions of consumers. Finally, the effectiveness of the proposed method was verified through IEEE 33 bus simulation.
