摘要:
为了有效评估风电接入后的电力系统惯量特性,定量把握风电场对电力系统的惯量贡献,提出一种通过量测风电场和 PCC 点有功功率和频率数据估计含风电电力系统等效惯量的方法。首先,推导了含风电惯量响应的电力系统等效惯量理论表达式;其次,以发电机为研究对象,建立不同扰动情况下机组惯量动态响应机理的统一解析表征模型;然后,通过有源自回归模型和基于改进粒子群优化卡尔曼滤波算法,估计在不同运行工况下同步机、风电场及系统的等效惯量;最后,在 IEEE 10 机 39 节点系统仿真验证所提方法的精确性和有效性。仿真结果表明,所提方法有效量化评估了风电机组等效虚拟惯量对系统等效惯量造成的影响。
Abstract:
In order to evaluate the inertia characteristics of the power system after the wind power is connected , the inertia contribution of the wind farm to the power system is quantified.This paper presents a method to estimate the equivalent inertia of power systems containing wind power by measuring the active power and frequency data at the point of common coupling ( PCC ) of wind farms and synchronous units.Firstly , the theoretical expression of equivalent inertia of power system with inertia response of wind power is derived ; secondly , the unified analytical and characterization model of the dynamic response mechanism of the inertia of the generator under different disturbance conditions is established by taking the generator as the research object ; then , the equivalent inertia of synchronous generator , wind farm and system under different operating conditions is estimated by using regression model and improved particle swarm optimization Kalman filter algorithm ; finally , the accuracy and effectiveness of the proposed method is verified in IEEE-10 machine 39-node system simulation.Simulation results show that the proposed method effectively quantifies the effects of the wind turbine equivalent virtual inertia on the system equivalent inertia.
