摘要
电动汽车和空调负荷等具有规模性和可控性,其大规模的使用会给电网的稳定性和安全性带来影响,合理地调控电动汽车和空调负荷有助于降低电网的调频调峰压力。对电动汽车和空调负荷的数学模型进行了分析,并对柔性负荷的特点进行了研究。建立了柔性负荷的目标函数以及电动汽车和空调负荷的约束条件。提出了一种改进的粒子群算法,该算法包括全局寻优过程和局部寻优过程,增强其跳出局部最优解的能力。算法仿真对比实验,验证了所提的改进粒子群算法具有较快的收敛速度和跳出局部最优解的能力。对配电网调度的仿真实验,验证了所提方法能够实现供需平衡,削峰调谷,有助于电网运行的稳定性和安全性。
Electric cars and air-conditioning loads are scale and controllable,and its large-scale use will affect the stability and security of the power grid.Reasonable regulation of electric vehicles and air conditioning load is helpful to reduce the peak pressure of the power grid.The mathematical models of electric vehicle and air conditioning load are analyzed,and the characteristics of flexible load are studied.The objective function of flexible load and the constraint conditions of electric vehicle and air conditioning load are established.This paper presents an improved particle swarm optimization(PSO)algorithm,which includes global optimization and local optimization.Simulation and comparison experiments show that the proposed improved PSO has fast convergence speed and the ability to jump out of local optimal solution.The simulation experiment of distribution network dispatching proves that the method proposed in this paper can achieve supply and demand balance,peak and valley clipping,and contribute to the stability and security of network operation.
