摘要
With the increase of prosumers having distributed energy resources in peer-to-peer markets, the network voltages may not remain within safe operating levels. Therefore, any peer-to-peer energy trading scheme must also take technical constraints into consideration in addition to economic benefits. This paper proposes a two-stage social welfare maximization approach which also includes network voltage management. A novel concept of limit trading has been introduced to enhance the value prosumers extract from peer-to-peer energy trading. The simplicity and prosumer-centric nature of this concept makes it quite practical for such trading scenarios. The proposed approach has been tested on IEEE-14 bus network and has been compared to two other approaches in three practical scenarios. The results show that it can improve the total social welfare of the community by up to 10 % without causing voltage issues. Moreover, the proposed approach performs better as compared to other methods in indices like Power Export Index and Jain's Fairness Index.
