含光伏蓄电池的冷热电联供系统运行模式评估

冷热电联供(CCHP)系统以其高效、清洁的特点而受到广泛的关注。将作为清洁能源和可再生资源的太阳能加入联供系统,可以进一步缓解能源危机和环境污染问题。为了提高分布式电源并网的稳定性,设计了一种可以平滑输出功率的光伏蓄电池系统,并将其与传统的CCHP系统相结合构建了一个综合型的联供系统。在热跟随(FTL)和电跟随(FEL)两种运行模式下,考虑电动汽车充电负荷的影响,评估环境成本和全寿命周期成本两个指标。

Mode assessment of CCHP system with photovoltaic-battery system

Combined cooling and heating system (CCHP) has attracted much attention with its efficient and clean features.To ease the energy crisis and environmental pollution problems,a clean and renewable resource solar is added to the cogeneration system.In order to improve the stability of distributed power grid,a photovoltaic-battery system was designed to smooth the output power.Combined the photovoltaic-battery system and traditional CCHP system,a comprehensive type of cogeneration system was built.Considering the impact of electric vehicle charging load,the environmental costs and life cycle costs were evaluated in following the electric load mode and following the thermal load mode.
