Abstract
Calculation model of on-grid distributed generation (DG) was put forward based on its influence on distribution equipment operation under stable condition and short-circuit fault.Taking security operation of main distribution equipment such as transmission lines,circuit breakers and protections as constraints,maximum permissible penetrated DG capacity was calculated and devices and related parameters restricting DG access were obtained.On this basis,weak adaptation point of distribution equipment had been located and corresponding improving measures had been put forward.Calculation result shows that adaptability of some individual devices is poor,greatly restricting distribution network capacity of accommodating DG.Aiming at this problem,this paper proposed a targeted reconstruction strategy to improve adaptability of distribution equipment by updating a few devices and validates effectiveness of this strategy with simulation ofa 10kV distribution network.关键词
