考虑风光荷联合作用下的电力系统经济调度建模
Modeling of Economic Dispatch of Power System Considering Joint Effect of Wind Power, Solar Energy and Load
摘要
Abstract
To solve the power dispatch problem caused by the uncertainties of wind power, photovoltaic generation and load, it is necessary to research economic dispatch of power systems including wind power and photovoltaic generation. This paper introduced the probability model of wind power, photovoltaic power and load forecasting error, constructed joint probability models considering the correlation among the random factors, established load loss risk model and economic dispatch model for typical operation modes. The constraint of load loss will replace the load missing probability constraint of dispatch models. The improved α-superquantile (α-SQ) was introduced, and Monte Carlo simulation and analytic method were combined to resolve optimal model with risk constraints. The simulation shows that, based on actual operational modes of power systems and correlation of randomness, the optimal dispatch results can be achieved at different confidence levels and different correlations of randomness, and optimal-economy can be achieved when the reliability of system is satisfied.关键词
