Dynamic Power Flow Calculation of Power System With Wind Power Generation Participating in Primary Frequency Regulation
摘要
Abstract
There is an increasing tendency for wind power generation to participate in primary frequency regulation (PFR). The PFR characteristics of wind turbines are different from those of conventional synchronous generators. Dynamic power flow is mainly used to simulate PFR process of power system under disturbance. Dynamic power flow calculation is composed of frequency calculation and conventional power flow calculation. Aiming at dynamic power flow calculation of power system with wind power generation participating in PFR, characteristics of variable-speed wind turbines participating in PFR with coordinated over-speed control and pitch control are established in this paper. Further, in frequency calculation of dynamic power flow, unbalanced power subsection distribution method is proposed, and one-level three-step Runge-Kutta (RK) method is employed to solve system frequency differential equations. In conventional power flow calculation of dynamic power flow, four new node types are proposed, and traditional Newton-Raphson algorithm is used to solve node power equations. Correctness and validity of the proposed method are verified in a modified IEEE 14 system, providing a basis for analysis and control design of the system with wind power generation participating in PFR.关键词
