Application of Swing Equation and Equal Area Criteria to Determine Maximum Penetration of Wind Generation in an Islanded Network

Abstract

The use of wind generation equipment, such as DFIG machines, interconnected to islanded power generation and distribution systems is investigated in order to determine the overall operating characteristics of the system and the effects this will have on overall stability. The use of a stable power station (high inertia machines) will be critical in achieving fast and reliable transient response to network events. This paper presents a simple method to determine rotor angle calculations and will outline the results of adding wind generation to islanded power networks and the effect these can have on stability. The results of this review assist in understanding how power stations and wind generation equipment respond to large transients in an islanded network. The simulations indicate that the use of wind generation (1.5 MW DFIG units) is viable and can assist with the stability of a small network.Grid System, Weak System, Wind Farm, Distributed Generation (DG), Islanded System, Rotor Angle, Equal Area Criteria (EAC), Double Fed Induction Generator (DFIG), Gas Turbine (GT)
