摘要
针对光伏电源接入中压配网的最大接入功率问题,在简化中压配网模型中分析了受母线电压及线路电流约束时光伏电源最大接入功率随配网PCC点电压变化的情况,并根据母线电压及线路电流随光伏接入功率变化的规律,推导影响光伏最大接入功率的PCC临界电压计算方法。经仿真验证,该方法准确性较高,适用范围较广。对光伏接入中压配网的规划和运行有一定参考价值。
This research focuses on the PV maximum power connected to medium-voltage distribution network. It ana- lyzes how the maximum access power, when restricted by bus voltage and line current, varies with the PCC voltage in the distribution network using a simplified medium-voltage distribution network model. Then the algorithm for PCC threshold voltage impacting PV maximum access power is derived based on the regular pattern how bus voltage and line current change with the PV access power. Simulation research has proved that this proposed method is accurate and applicable on a wider scale, and the research results may provide available reference to the planning and opera- tion of PV access to medium-voltage distribution network.
