摘要:
      针对光伏电源接入配电网带来的电压越限问题,本文考虑空调负荷的调节潜力,提出一种基于光伏与空调负荷协调优化的有源配电网经济调压策略。首先,光伏与空调负荷根据自身利益建立各自调节量-调节成本模型;其次集中控制器根据各用户的模型及潮流、网损等信息,以经济性为目标,优化分配各用户的实际调节量。将空调负荷的调节能力与光伏的调节能力协调配合,在实现电压调节的同时,减少或避免切除光伏的有功出力。仿真分析结果表明,所提策略在有效调节电压的同时,减少了网损,兼顾了光伏、空调负荷、负荷集中商及电网公司的利益,具有较高的经济性。
Abstract:
      Aiming at the problem of voltage over-limit caused by photovoltaic power that supply to the distribution network, this paper considers the adjustment potential of air-conditioning load, and proposes an economic regulation strategy for active distribution network based on coordinated optimization of photovoltaic and air-conditioning load. First of all, the adjustment amount-cost model of the PV and air conditioning load are established according to their own interests; secondly, the centralized controller is used to optimize the actual adjustment amount of each user according to the model of each user and the trend, the network loss and other information. Meanwhile, this strategy coordinates the adjustment capability of the air conditioning load with the adjustment capability of the photovoltaic, and reduces or avoids the active output of the photovoltaic while achieving voltage regulation. The simulation results show that the proposed strategy can reduce the network loss while effectively adjusting the voltage, taking into account the interests of photovoltaic, air conditioning load, load aggregator and Power Grid Company, and has high economic efficiency.
