Abstract

The invention belongs to the technical field of power system automation, and particularly relates to a multi-target day-ahead optimal scheduling method for a multi-power-supply power system. The method comprises the following steps: (1) obtaining a system operation mode, load prediction data and renewable energy power generation prediction data of the next day; (2) establishing a multi-target day-ahead optimal scheduling model of the multi-power-supply power system; (3) solving the model by adopting a particle swarm optimization algorithm; and (4) generating a day-ahead scheduling strategy according to a solving result. According to the method, the operation characteristics of various types of generator sets can be comprehensively considered, a day-ahead optimization scheduling scheme which meets the safety requirement, makes full use of renewable energy sources and is reasonable in economy is formulated, safe and economic operation of a power system is ensured, and meanwhile, the renewable energy source consumption level is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a multi-objective day-ahead optimization scheduling method for a multi-source electric power system. Background technique [0002] In recent years, with the rapid development of renewable energy, wind power and photovoltaic power generation technologies have become increasingly mature, and installed capacity has continued to increase. Among them, wind power is one of the power generation methods with the most mature technology, the most large-scale and commercial development value. However, due to the uncertainty of the primary energy of renewable energy, the output power of wind power and photovoltaic will fluctuate randomly within a wide range. The continuous improvement of the penetration rate of new energy power generation will bring new challenges to the peak regulation of the power system, the stability of the power grid and the economi...
