现有电力系统潮流追踪计算方法在含有电、气、热等多能源耦合的综合能源系统中存在局限性。㶲作为多种能源形式的共有属性,能够统一表征综合能源系统的有效能。为明晰综合能源系统中有效能在网络中的流动踪迹,文中基于等效㶲流机理模型建立了综合能源系统㶲流追踪模型,分别提出了综合能源系统顺序㶲流追踪方法、逆序㶲流追踪方法和㶲流分配解析追踪方法。通过典型综合能源系统算例,全面分析了综合能源系统网络中㶲流在源-网-荷的分配关系,并验证了㶲流追踪模型的正确性。最后,对㶲流追踪在能源价格制定、可再生能源消纳路径、不良㶲数据辨识、规划与运行优化等方面的应用前景进行了展望。
The power flow tracing calculation method for power systems has limitations for integrated energy systems (IESs) containing multiple coupling energy sources such as electricity
gas and heat. Exergy
as a common property of multiple energy forms
can uniformly characterize the effective energy of an IES. In order to find the traces of effective energies flowing in the network of the IES
this paper establishes an exergy flow tracing model for IES based on the equivalent exergy flow mechanism model. And the exergy flow tracking methods of upstream-looking
downstream-looking
and exergy flow distributing parse are proposed. By using a typical IES case
this paper comprehensively analyzes the exergy flow distribution relationship between source
grid and load in the IES
and verifies the correctness of the exergy flow tracing model. Finally
the application prospect of exergy flow tracing in energy price setting
renewable energy accommodation path
identification of bad exergy data
and planning and operation optimization is presented.
