摘　　要：针对传统电化学储能造价高导致我国可再生能源消纳困难问题,提出一种考虑电-热储能协同的综合能源系统最优化规划方法。分析铅酸电池和蓄热罐的物理特性,建立其状态表征模型;设计电-热储能系统融合平抑可再生能源出力波动、保障供需平衡、峰谷套利三种功能场景的协同运行策略,建立考虑电-热协同的规划优化策略;基于最优化理论,以年总成本最小为优化目标,提出一种考虑电-热储能协同的综合能源系统规划优化模型,并以改进粒子群算法对模型进行求解。算例结果表明,所提出的模型能够有效提升能源系统的可再生能源消费占比。The proposal of the“30·60”dual carbon target and construction of a new power system with new energy as the main body has promoted the rapid development of renewable energy in China.However,the grid connected regulation of renewable energy,mainly based on wind and light,remains the main limit factor for its development,which has had a significant impact on winter heating in the“Three North”regions of China.Configuring energy storage batteries can to some extent alleviate the problem of grid connected consumption of new energy.Electric energy storage equipment has a fast response speed and can effectively cope with power fluctuations generated by renewable energy output,which to some extent solves the problem of renewable energy output fluctuations.But its high cost increases the cost of energy consumption.The unit cost of thermal storage equipment is low,which can better absorb electricity and respond to peak and valley electricity prices,reducing energy usage costs.Coupling electric energy storage with thermal energy storage can fully utilize the advantages of electric and thermal energy storage to achieve optimal system configuration.With the continuous promotion of the“30·60”dual carbon target,solving the problem of renewable energy consumption from the perspective of comprehensive energy systems has become a hot research topic.The integrated energy system couples different types of energy together to achieve collaborative and comprehensive utilization of different types of energy,thereby reducing the impact of new energy grid connection on the power grid.In view of this,in response to the problem with a high cost of traditional electrochemical energy storage leading to difficulties in the consumption of renewable energy in China,this article proposes an optimization planning method for comprehensive energy systems from the perspective of integrated energy systems,considering the synergy between electricity and thermal energy storage.Firstly,the physical characteristics of lead-acid batteries and
