Study on the Benefit from Spinning Reserve in Wind Power Integrated Power System Based on Conditional Value at Risk
摘要
Abstract
Due to the fluctuation and intermittent of wind power,large-scale wind power grid connection makes the contradiction between the spinning reserve benefit and risk more prominent.The capacity cost and the energy cost of the system up and down spinning reserve,the reduced power loss due to the purchase of up spinning reserve and the reduced wind loss due to the purchase of the down spinning reserve are considered.To establish the spinning reserve benefit-risk model of wind power integrated system based on conditional value at risk(CVaR) with the goal of maximum expected spinning reserve benefit and minimum CVaR value of system loss.Monte Carlo method is used to simulate the actual load power and wind power prediction error,and the multi-objective particle swarm optimization algorithm is improved to find the efficient frontier of expected spinning reserve benefit-risk and the day-ahead spinning reserve plan,and the influence of different reliability level and confidence level on expected spinning reserve benefit and risk.Finally,the example shows the feasibility of the model and the algorithm.关键词
