摘　　要：文章基于电网无功定价理论和电网稳定约束,结合IEEE14节点的典型接线进行新能源并网的模拟;采用牛顿算法得出新能源并网后导致的有功、无功增量的变化,由此求得各节点的有功、无功成本变化趋势;分析了各电能供应商对改善全网的电压稳定性所付出的无功支撑成本;论证了采用无功定价方法对新能源并网后的无功服务的合理补偿,可起到平衡各方利益的作用,对新能源的就地消纳产生积极的影响。文章可为新能源融入地方电网实现一体化的稳定运营提供市场交易的理论支撑;为制定无功服务定价提供参考;为实现新能源并网后的电力系统安全运行奠定基础。The paper simulate the new energy grid with the typical wiring of IEEE4 node based on the power pricing theory and power grid stability constraints.We conduct the change of active and reactive incremental after the new energy grid using the Newton algorithm,thus obtained the cost of changing trends.And then analyze the reactive power support costs of the electricity supplier for improving the voltage stability of the entire network.Studies show that the reasonable compensation of reactive power pricing method will balance the interests of all parties, and have a positive impact on new energy consumptive.The results provide theoretical support for the stable operation of the integration of new energy into the local grid,and also lay the foundation for power system safe operation.
