摘要:针对供暖清洁化改造与新能源消纳，提出增加电/热储能的配置以提高多能源系统的灵活性，以运行成本最低为目标函数构建了包含光伏、电化学储能、蓄热罐、电锅炉的多能流清洁供暖容量配置优化模型，基于DeST进行建筑供热负荷精细模拟，运用智能算法对系统在并/离网运行策略下不同场景各能量单元容量配置进行计算。受制于运行调度策略设置与成本限定，场景一并网运行策略下，仅配置光伏电站，运行成本最低。场景二自由购电与余电弃用策略下，相较场景一减少光伏配置，增加少量储热以减少供热低谷与光伏高出力叠加时段的光伏弃电。场景三在离网运行与新能源消纳限定条件下，电化学储能的大规模配置提高了系统的自给能力，成本较场景一、二大幅提升147.8%、111.9%，新能源浪费率由77%下降至50%，自给能力大幅提升。
Abstract：Aiming at the transformation of heating cleaning and new energy consumption, it is proposed to increase the configuration of electric/thermal energy storage to improve the flexibility of the multi-energy system. A photovoltaic, electrochemical energy storage, thermal storage tank and electric boiler are constructed with the goal of the lowest operating cost. Based on DeST carry out fine simulation of building heating load, and use intelligent algorithm to calculate the capacity configuration of each energy unit in different scenarios under the on-grid/off-grid operation strategy. In different scenarios, it is subject to operation scheduling strategy settings and cost constraints, Under the grid-connected operation strategy of Scenario 1, only photovoltaic power plants are configured, and the operating cost is the lowest. In Scenario 2, under the strategy of free power purchase and surplus electricity disposal, compared with Scenario 1, the PV configuration is reduced, and a small amount of heat storage is added to reduce heating troughs and photovoltaics. In the case of photovoltaic power abandonment during the period of high output superposition, the large-scale configuration of electrochemical energy storage improves the self-sufficiency of the system under the limited conditions of off-grid operation and new energy consumption in scenario three, and the cost is greatly increased by 147.8%, 111.9% compared with Scenarios 1 and 2. The new energy waste rate drops from 77% to 50%, and the self-sufficiency is greatly improved.
