电力市场环境下风光储联合运行优化策略

摘要

风电、光伏等新能源机组与储能系统联合参与电力市场竞争的策略,有利于提高新能源发电企业的市场竞争力,促进新能源消纳与友好接入.构建风电一光伏—储能联合优化运行决策模型,以利润最大化为目标,充分考虑新能源机组与储能系统运行时的各项技术约束条件,研究在电力市场环境下风光储协调耦合运行的发电策略与出力安排,并分析联合运行模式所带来的经济效益问题.算例分析验证了所提出的风光储联合运行优化决策模型的正确性与有效性.%It is of great importance to explore the optimal strategy of wind-PV-ES hybrid operation in the electricity market,which can increase the competition of the renewable generation companies and promote the accommodation and integration of renewable energy.A wind-PV-ES hybrid system was established with the purpose of profit-maximization in this paper,and various technical constraints under normal operation of renewables units and storage system were considered.Generation stratage and output dispatch under wind-PV-ES coordinated coupling operation in electricity market was researched,and then the economic benefits brought by joint operation mode were analyzed.Finally,examples were analyzed,results verified the optimal strategy model ofwind-PV-ES hybrid operation.
