Abstract

The invention provides an electric power system operation risk assessment method based on scenario analysis. The method includes: using the Latin hypercube sampling method for scenario generation of equivalent load; performing scenario reduction based on Kantorovich distance; and calculating scenario analysis based electric power system operation risk assessment indexes. Scenario generation and scenario reduction are adopted simultaneously to represent wind power capacity and load uncertainty, decision making risk indexes are calculated by the aid of a semi-absolute deviation model in the investment combination theory, and the method has the advantages of more comprehensiveness and reasonableness.

Description

technical field [0001] The invention belongs to the field of electric power system scheduling automation, and in particular relates to a method for evaluating the risk of electric power system operation based on scenario analysis. Background technique [0002] Energy-saving power generation scheduling has changed the traditional power generation scheduling method, canceling the practice of allocating power generation indicators according to administrative plans, aiming at energy saving and environmental protection, and taking the internal generation, transmission, and power supply equipment of the entire power system as the scheduling object, and prioritizing the scheduling of renewable and Clean power generation resources, according to energy consumption and pollutant discharge levels, use fossil power generation resources in order from low to high, minimize energy, resource consumption and pollutant discharge, and promote efficient and clean operation of the power system. ...
