A New Energy Priority Scheduling Method Based on Two-Stage Unit Combination

Abstract

The invention discloses a new energy priority scheduling method based on the two-stage set combination. The method comprises the steps that basic parameters required by the power generator set combination are acquired; power generator sets are divided into slow sets and fast sets according to the length of start-stop time; the initial time T0 of the long-time set combination is set, and a new energy output prediction sequence value and a system spare capacity configuration sequence value suitable for the long-time set combination are determined; the power generation schedule of each power generator set in the following 120h is determined; the initial time TT0 of the short-time set combination is set, and the new energy output prediction sequence value and the system spare capacity configuration sequence value suitable for the short-time set combination are determined; and the power generation schedule of each power generator set is corrected. According to the method, new energy priority scheduling can be further optimized and the new energy operation level can be enhanced.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a new energy priority scheduling method based on two-stage unit combinations. Background technique [0002] At present, vigorously developing renewable energy such as wind power and solar energy is an important measure for the country to implement energy conservation and emission reduction strategies to achieve sustainable energy development. At present, most countries generally adopt policy support methods such as price subsidies for wind power and priority dispatching of wind power to encourage the development of wind power. my country has successively promulgated the "Renewable Energy Law of the People's Republic of China", "Measures for Energy-Saving Power Generation Dispatch <Trial Implementation>", "Amendment to the Renewable Energy Law of the People's Republic of China", etc., and formulated specific measures for the priority dispatch of renewable energy. Thes...

Problems solved by technology

However, the existing work has the following main problems: determining the power generation plans of various power sources according to the average power generation hours in the same provincial power grid, emphasizing the balance of interests, which is not conducive to the priority consumption of new energy sources, and focusing on mathematical modeling without fully considering Coal-fired units are the main conventional power sources in my country's wind power-rich provinces, which have the characteristics of long start-up time and poor operation flexibility, and the physical effect is not good
