摘要:
      针对分布式热电联供系统与外部电网联络线全周期功率波动问题,提出了基于虚拟电池模型的分布式热电联供系统全周期功率波动平抑策略。该策略首先根据热负荷的动态约束建立气态虚拟电池模型,并与液态虚拟电池模型和电池储能模型共同构成电网统一模型下的虚拟电池综合储能系统。然后将分布式热电联供系统全周期功率波动平抑问题等效成一个最短路径优化问题,并采用改进Dijkstra算法,通过调控虚拟电池综合储能系统的荷电状态对其进行求解。在理论研究的基础上,利用实际的户用能源管理系统对所提出的全周期功率波动平抑策略进行测试。结果表明,所提策略能够平抑分布式热电联供系统全周期功率波动,实现电池储能、液态热储能和等效气态热储能的协同调度。
Abstract:
      To solve the complete-period tie-line power fluctuation problem of the distributed combined heat and power(DCHP)system, a complete-period power fluctuation suppressing strategy based on virtual battery model is proposed. Firstly, a virtual gas-battery energy storage model is established according to the dynamic constraints of heat loads, and it is combined with the virtual liquid-battery energy storage model and the battery energy storage model into a virtual battery integrated energy storage system under united architecture of the power grid. Secondly, the complete-period power fluctuation suppressing problem is simplified into a shortest path optimization problem. This problem is solved by the state of charge(SOC)dispatching strategy of the virtual battery integrated energy storage system by using the improved Dijkstra algorithm. Based on the theoretical analysis, the proposed strategy is tested by the practical household energy management system. Finally, test results show that the proposed strategy can suppress the complete-period power fluctuation of DCHP system and realize the co-scheduling of battery energy storage, virtual liquid energy storage and virtual gas energy storage.
