Meteorological-energy-contained integrated energy system typical scene set generation method

Abstract

The invention relates to a meteorological-energy-contained integrated energy system typical scene set generation method, and belongs to the technical field of electric power system operation and analysis. The meteorological-energy-contained integrated energy system typical scene set generation method is characterized in that modeling is performed on the meteorological correlation based on a Copula function theory and a Latin hypercube sampling theory; the correlation between meteorological variables is fully considered; the algorithm can significantly improve accuracy of random production simulation of the meteorological variables; and an optimal quantile theory based on Wasserstein distance is used to perform discretization on randomly simulated continuous variables to obtain a small number of integrated energy system typical scene sets. In the meteorological-energy-contained integrated energy system typical scene set generation method, the optimal quantile theory can generate extreme scenes and can greatly improve the calculating precision. The optimal quantile theory utilizes the discrete variables to enable the meteorological-energy-contained integrated energy system typical scene set generation method to be distinguished from other existing research results. The generated typical scene sets can help an operator to analyze the problem brought to operation and planning of the integrated energy system by nondeterminacy, and the analysis result of typical scenes can provide support for safe and stable running of the system.

Description

technical field [0001] The invention relates to a method for generating a typical scene set of a comprehensive energy system including meteorological energy, and belongs to the technical field of power system operation and analysis. Background technique [0002] With the increasingly severe energy and environmental problems, in order to improve the overall efficiency of energy and the ability to accommodate renewable energy, there is an increasingly urgent need for the integration and complementary integration of multiple energy systems. With the development of various energy system technologies, the coupling degree of power system and heating and cooling system has been continuously enhanced, forming a comprehensive energy system of cooling, heating and power. There are three significant differences between the integrated energy system with high-penetration meteorological energy and the traditional power system: the increasing proportion of intermittent renewable energy and...
