摘要
多能互补园区能实现能源的梯级利用,可有效地进行多种能源的协调调度,进而提高用能效率和用能可靠性,因此被广泛应用。基于电转气技术和供能分区多主体特性,提出了一种计及电转气的多能互补园区供能分区优化调度方法。综合考虑多能互补园区供能分区的供能经济性、环保经济性以及风电、光伏出力特性,建立基于非合作博弈的双层优化调度模型,上层以日运行成本最低为目标函数,下层以风电、光伏出力特性最优为目标函数,利用非合作博弈理论研究园区内部各分区之间的多主体特性优化调度。算例分析结果验证了模型的有效性,实现了对多能互补园区供能分区的优化调度。
Multi-energy complementary parks are widely used because they can realize the cascade utilization of energy and effectively coordinate and dispatch multiple energy sources,thereby improving energy efficiency and reliability.Based on the power to gas technology and the multi-agent characteristics of energy supply zoning,this paper proposes an optimal dispatching method for multi-energy complementary parks supply zoning,which takes into account power to gas.Comprehensively considering the energy supply economy,environmental protection economy and wind power/photovoltaic output characteristics of the multi-energy complementary parksupply zoning,a double-layer dispatch model based on non-cooperative game is introduced.The upper layer takes the lowest daily operating cost as the objective function,and the lower layer takes the wind power and photovoltaic output characteristics optimal as the objective function,and the non-cooperative game theory is used to study the optimal scheduling of multi-agent characteristics among the internal zones of the park.The analysis result of the calculation example verifies the validity of the model and realizes the optimal scheduling of the multi-energy complementary park supplying zoning.
