摘要
储能有助于可再生能源消纳,但单一的储电、储气都有局限性。本文研究了储电与储气的协调运行策略,建立了电气混合储能系统的数学模型,分析了其消纳弃风原理,并在协调运行策略基础上,建立了考虑电气混合储能的区域能源系统优化调度模型。结合算例对比分析了不考虑储能装置、考虑电转气(P2G)与储气装置、储气-储电常规运行和储气-储电协调运行4种场景下的风电消纳效果和经济性。结果表明,本文提出的储气-储电协调运行策略可以有效提高系统经济性和可再生能源消纳能力。
Energy storage is conducive to the consumption of renewable energy,but a single storage of electricity and gas has limitations.In this paper,the coordinated operation strategy of electricity storage and gas storage is studied,the mathematical model of electric hybrid energy storage system is established,and the principle of absorbing and discarding wind is analyzed.Moreover,based on the coordinated operation strategy,the optimal operation model of regional energy system considering electric hybrid energy storage is established.The wind power consumption effect and economy under the four scenarios of not considering energy storage device,considering power to grid(P2G)and gas storage device,conventional operation of gas storage power and coordinated operation of gas storage power are analyzed.The results show that,the coordinated operation strategy of gas storage and electricity storage proposed in this paper can effectively improve the system economy and renewable energy capacity.
