Research on Multi-objective Planning of Active Distribution Network Considering Energy Storage Operation Strategy

With the reform of the power market, the distribution network side is gradually released, and the investment on the distribution network side has a huge impact on the distribution network planning. In particular, investment in energy storage has become the focus of investment in distribution networks in recent years. This paper establishes a comprehensive evaluation system for active distribution network planning considering economic, environmental protection, power supply quality and safety assessment. The grid companies and third-party companies are used as different investment entities to analyze the energy storage operation strategy. Based on the comprehensive evaluation system and energy storage operation strategy, a multi-objective optimization model for distribution energy resource in active distribution networks was established. Finally, the example is simulated by using the "2 supply and 1 standby" medium voltage distribution network topology. The simulation results verify the feasibility ADN effectiveness of the model.
