本文根据分布式电源对配电网的有功损耗和电压稳定与分布等方面的影响,针对含分布式电源的配电网,构建以节点电压合格率最高为目标的电压无功优化模型,然后结合配电网负荷变化及太阳能容量的变化特点,选取一天中3个典型的负荷点,采用多种电压无功调节装置(OLTC、SVR、SC和SVC)组合优化的策略对配电网电压进行优化控制,并采用收敛性较好的遗传算法求解最优电压,最后通过算例仿真分析几种电压无功调节装置不同组合情况下的电压优化效果,验证了几种组合方法均能对配网电压起到优化作用的正确性。
In this paper, according to the influence of distributed power on active power loss and voltage stability and distribution in distribution network, aiming at the distribution network with distributed generation, a voltage and reactive power optimization model aiming at the highest node voltage passing rate is built, Distribution network load changes and solar energy capacity changes, select three typical load points a day, the use of a variety of voltage and reactive power regulation device (OLTC, SVR, SC and SVC) portfolio optimization strategy to optimize the distribution network voltage Control, and use the genetic algorithm with better convergence to solve the optimal voltage. Finally, the voltage optimization effect of several voltage and reactive power adjustment devices under different combinations is simulated and analyzed by a numerical example. Play a role in optimizing the correctness.
