摘要:

随着配电网复杂性日益增加以及对电能质量要求不断提高,谐波污染和网络损耗已成为影响新型电力系统稳定性和运行效率的关键因素。通过同步优化电容器和有源功率滤波器(active power filter,APF)的配置,实现谐波抑制与网络损耗最小化的双重目标。利用谐波功率流分析模型进行谐波评估,根据谐波穿透法进行频域建模。对失真配电网络中的电容器和APF的同步配置建模,利用粒子群优化(particle swarm optimization,PSO)算法解决电容器和APF同步配置的混合整数非线性规划问题。实验结果表明:适当配置电容器和APF能够显著改善网络的电压质量,所提的同步优化方法不仅在降低系统成本的同时,显著提高了新型电力系统配电网的电能质量和运行效率。

Abstract:

With the increasing complexity of distribution networks and the growing demand for power quality, harmonic pollution and network losses have become key factors affecting system stability and operational efficiency. This paper proposes an innovative approach based on the particle swarm optimization (PSO) algorithm, aimed at simultaneously optimizing the configuration of capacitors and active power filter (APF) to achieve the dual objectives of harmonic suppression and network loss minimization. First, a harmonic power flow analysis model is used to assess harmonics, with frequency-domain modeling based on the harmonic penetration method. Then, the simultaneous configuration of capacitors and APF in the distorted distribution network is modeled, and the mixed-integer nonlinear programming problem of optimizing the simultaneous configuration of capacitors and APF is solved using the PSO algorithm. Experimental results show that proper configuration of capacitors and APF significantly improves the network's voltage quality, the proposed synergistic optimization method not only reduces system costs but also significantly improves the network's power quality and operational efficiency.

Key words: harmonic power flow, distribution network quality, network loss
