摘要 该文以实现多类型能源的协同优化、微能源系统的运行效益最优为出发点,在包含光伏发电、储能系统、蓄热式电锅炉、冰蓄冷空调、电动汽车的微能源系统的简化模型基础上,对微能源系统中储能系统容量规划和投资效益展开研究。首先为保证微能源系统的各类型能源的生产/消费需求,假设分别为其配置虚拟储能,基于储能系统成本、多种类型能源的生产/消费需求约束及储能系统约束,同时考虑峰谷分时电价、碳减排政策,进行多目标优化求解实现储能容量配置最优,并从投资人角度出发,考虑银行贷款、内部收益率等投资回收相关参数,对储能系统进行投资回收分析。最后结合某微能源系统示范工程,开展新型混合能源系统配置方案的应用验证,旨在探索微能源系统中储能系统的优化配置方案。

Abstract:In order to achieve synergistic optimization of multiple types of energy and optimal operation efficiency of micro-energy systems, this paper established a simplified model of micro-energy system including photovoltaic power generation, energy storage system, regenerative electric boiler, ice storage air conditioner and electric vehicle. The configuration and investment benefit of the battery energy storage system in the micro-energy system were analyzed. Firstly, this paper assumed that each type of energy in a micro-energy system is configured with virtual energy storage to ensure its production/consumption needs. Then, based on the cost of energy storage system, the production/consumption demand constraints of various types of energy and the constraints of the energy storage system itself, a multi-objective optimization solution is performed to achieve optimal storage capacity allocation by taking into account the peak-to-valley time-of-use electricity price and carbon emission reduction policy. From the perspective of investors, consider the relevant parameters of investment recovery such as bank loans and internal rate of return, this paper analyzes the investment recovery of energy storage systems. Finally, combined with a micro-energy system demonstration project, the application verification of the new hybrid energy system configuration scheme was carried out to explore the optimal configuration scheme of the energy storage system in the micro-energy system.
