Comprehensive diagnosis method and system for electrothermal micro-network topology based on complex network

Abstract

The invention relates to a comprehensive diagnosis method and system for an electrothermal micro-network topology based on a complex network. Static diagnosis and dynamic diagnosis are sequentially carried out after performing decoupling and modeling on an electrothermal coupled network, and finally energy allocation and node expansion optimization are carried out on the electrothermal coupled network according to the diagnosis result. According to the invention, the coupled network is decoupled and modeled by taking a multi-node coupling model as a basis and fully considering the characteristics of the network structure, and the network topology static diagnosis method and dynamic diagnosis method can be applied to the multi-node coupling complex network diagnosis, thereby providing an index reference for the optimization and expansion of the electrothermal micro-network topology in the practical application process.

technical field [0001] The invention relates to a technology in the field of smart grid control, in particular to a method and system for comprehensive diagnosis of electric heating micro-grid topology based on complex networks. Background technique [0002] As a typical heterogeneous network, the electric heating microgrid contains two energy flows of electric energy and thermal energy, which are supplied and distributed through power lines and heat flow pipes respectively. Different from a single power grid or heating network, the two networks of the electric heating micro-grid operate at the same time and have a coupling relationship, so as to realize complementary utilization of energy and improve energy efficiency. However, as a typical heterogeneous network, the electrothermal microgrid contains two energy flows of electric energy and thermal energy. The two networks operate simultaneously and have a coupling relationship. The existing methods only target a single powe...

Problems solved by technology

However, as a typical heterogeneous network, the electrothermal microgrid contains two energy flows of electric energy and thermal energy. The two networks operate at the same time and have a coupling relationship. The existing methods only target a single power network, and it is difficult to comprehensively diagnose the topology of the electrothermal microgrid.

The diagnosis of the existing electric heating microgrid mostly refers to reliability, faults, etc., and lacks effective diagnosis for the topology of the energy supply network, and the topology is the key to the planning, design and operation of the electric heating microgrid
