摘要
为解决新型电力系统中高比例可再生能源接入后电网节点的电压问题,提出一种考虑重力储能的电网无功优化及电压控制方法。从理论层面分析了重力储能功率模型和重力储能无功补偿原理,建立了以节点电压总偏差最小为目标函数的无功优化和电压控制数学模型,以潮流、系统运行和储能功率作为约束条件,采用基于竞争机制的粒子群优化算法进行求解。仿真算例验证,该方法具有实用性和有效性。
A reactive power optimization and voltage control method considering gravity energy storage is proposed in order to solve the voltage problem of power grid after a high proportion of renewable energy is connected into the new type power system.Analyzes the power model and the reactive power compensation principle of gravity energy storage theoretically,and establishes the mathematical models of reactive power optimization and voltage control with the minimum total deviation of node voltage as the objective function.Taking power flow,system operation conditions and energy storage power as constraints,the particle swarm optimization algorithm based on competition theory is used to solve the equation.The effectiveness and practicability of the proposed method are verified by simulation examples.
