摘　　要：为解决能源短缺等问题,各国为可再生能源的发展给予大力支持。但由于可再生能源具有随机性、波动性等特点,难以进行运行调控。如何增大可再生能源的消纳成为当下的研究热点。该文针对风电消纳问题进行研究,将电锅炉、电转气技术及储能设备引入综合能源系统中,并考虑电力需求响应负荷。系统总成本中考虑设备投资与运维成本、购电与购气成本,建立综合能源系统经济优化调度模型。利用mosek求解器对模型进行求解。针对文中提出的4种方案,以算例验证方案可行性。对比分析得出风电消纳最大,系统费用最小的方案。In order to solve the problem of energy shortage,all countries provide strong support for the development of renewable energy.However,due to the randomness and volatility of renewable energy,it is difficult to control operation.How to increase the consumption of renewable energy has become a current research hotspot.This paper studies the wind power consumption problem,introduces electric boilers,power-togas technology and energy storage equipment into the integrated energy system,and considers the power demand response load.The total system cost considers equipment investment,operation and maintenance costs,electricity and gas purchase costs.This article establishes a comprehensive energy system economic optimization dispatch model.Use mosek solver to solve the model.Aiming at the four schemes proposed in the article,examples are used to verify the feasibility of the scheme.The comparative analysis shows the scheme with the largest wind power consumption and the smallest system cost.
