Problems solved by technology

[0003] The comprehensive energy operation quality analysis based on the energy hub is an important means to improve system performance, but there is currently a lack of a complete evaluation system. When wind power, photovoltaics, energy storage and other types of equipment are connected to the system, the system's operation quality analysis becomes more complicated. Bringing difficulties to intelligent operation and maintenance

Abstract

The invention provides a collaborative operation quality analysis system for an energy hub, and the system comprises an obtaining module which is used for obtaining the historical data information of the abnormal work of each module in the energy hub; an analysis module which is used for receiving the acquisition information of the acquisition module, performing analysis and calculation according to the acquisition information, and acquiring a relative factor Di of an abnormality probability of the ith module of the energy hub and an abnormality probability of other modules of the energy hub; a quality evaluation module which is used for calculating an evaluation coefficient S of the energy hub in the current state based on the relative factor Di of each module in the M modules in the energy hub, and S=(S1)<2>*logD(1)+(S2)<2>*logD(2)+... +(Si)<2>*logD(i)+... +(SM)<2>*logD(M); wherein Si is the state of the ith module in the current state, the value range is -10-0, the evaluation coefficient of the operation quality of the energy hub in the current state can be calculated through the analysis system, and the cooperative operation quality of all the modules of the current energy hub is evaluated according to the numerical value of the evaluation coefficient.

Description

technical field [0001] The invention generally relates to the field of electric power technology, and in particular to an energy hub collaborative operation quality analysis system. Background technique [0002] As a major development strategy of my country's future energy, comprehensive energy has attracted extensive attention from the power industry. Compared with the traditional power system, the integrated energy system has obvious differences in user behavior, operation method, demand response, etc. Through the coupling and linkage of various types of energy, the market width, time scale and geographical dimension of the traditional power industry have been expanded . Energy hub (Energy Hub, EH) is a collection of various forms of energy consumption such as energy storage, combined cooling, heating and power supply, and loads. It is a key link in building an integrated energy system. [0003] Comprehensive energy operation quality analysis based on energy hubs is an i...
