摘要
Abstract
Stochastic production simulation is an important method for reliability evaluation for the hydro-thermal generation system. On the premise of considering impact of maintenance schedule for hydro-thermal generator on reliability evaluation for the generation system, this paper presents an interval-coordinated stochastic production simulation method for dividing the study period into intervals according to maintenance state of the generator. By coordinating different time periods, this method can determine working capacity of the hydro-thermal generator and then make stochastic production simulation on the generator in each time period independently. Since simulation order of the full-capacity generator has no influence on the residual load duration curve and reliability index, this paper preferentially simulates the thermal generator and then the hydro generator, which can avoid searching economy load position and greatly improve computation speed of reliability evaluation. Testing results of one small system and an actual provincial power grid verify validity and computation speed of the proposed method.关键词
