当前电热综合能源网研究大多基于传统热网,并局限于由少量热电联供机组构成的弱耦合网络。第5代区域供热供冷系统驱动的能源元胞可通过热泵池实现高密度网状融合的电热网,改变电热网交互形态。论述了第5代区域供热供冷系统给综合能源电热耦合网统一建模理论带来的重大机遇和挑战,以及基于第5代区域供热供冷系统的能源元胞灵活性聚合的广阔应用前景。进一步,综述了第5代区域供热供冷系统的研究现状、电热耦合网多能流建模理论及分布式资源的灵活性聚合方法。针对能源元胞利用热泵池与热网热惯性提升电网灵活性的契机,提出第5代区域供热供冷系统驱动的能源元胞网络流理论与灵活性聚合方法的研究思路:热动态从热泵池到配电网的交互机理与可行域分析、异质性智慧能源元胞互联的灵活性聚合与分配的分层级协调优化方法。
At present
the research of electricity-heat integrated energy networks is mostly based on the traditional heat network and limited to the weak coupling network composed of a small number of combined heat and power units. The energy cells driven by the 5th generation district heating and cooling (5GDHC) system can realize the high-density mesh integrated electricity-heat network through the heat pump pool and change the interactive form of the electricity-heat network. This paper discusses the great opportunities and challenges brought by the 5GDHC system to the unified modeling theory of integrated energy electricity-heat coupling network
and the broad application prospect of energy cell flexibility aggregation based on the 5GDHC system. Furthermore
the research status of the 5GDHC system
the multi-energy flow modeling theory of electricity-heat coupling network
and the flexibility aggregation method of distributed resources are summarized. Aiming at the opportunity of energy cells using the heat pump pools and the heat network thermal inertia to improve the flexibility of the power grid
the research idea of energy cell network flow theory and flexibility aggregation method driven by the 5GDHC system are proposed: the interaction mechanism and feasible region analysis of thermal dynamics from heat pump pool to distribution network and hierarchical coordinated optimization method for flexible aggregation and allocation of heterogeneous smart energy cell interconnection.
