风-光互补发电系统是开放的、分布式系统,适合采用多Agent技术进行分散式决策、分散式控制。根据电压与无功功率和有功功率的关系,建立了考虑电压稳定的以有功损耗最小为目标的电压无功优化控制模型,并提出一种基于均匀设计和惰性变异的改进粒子群算法用于该模型的求解;建立了风-光互补发电系统电压控制系统的自动机模型。仿真实验显示,电压优化控制模型和改进的粒子群算法能够有效实现电压无功优化控制,电压控制系统的自动机模型能够及时跟踪电压变化,实现电压自动控制。
Wind-light complementary power generation system is an open, distributed system suitable for distributed decision-making and decentralized control using multi-agent technology. According to the relationship between voltage and reactive power and active power, a voltage and reactive power optimization control model with minimum active loss considering voltage stability is established and an improved particle swarm optimization algorithm based on uniform design and inert mutation is proposed Model was established. The automaton model of voltage control system of wind-solar power system was established. Simulation results show that the voltage optimization control model and the improved particle swarm optimization can effectively control the voltage and reactive power. The automatic model of the voltage control system can track the voltage changes in time and realize the automatic voltage control.
