The invention discloses a CCHP (combined cooling, heating and power) system coordinated scheduling method under an active power distribution network environment. The coordinated scheduling method is applied when a CCHP system is accessed to the active power distribution network and operates to solve the coordination problem between power distribution network reconstruction optimization and CCHP system economical optimization targets. The coordinated scheduling strategy is used for carrying out system optimization on the whole system comprising CCHP system subsystems. Therefore, through the artificial intelligence technology, the method can provide flexible, safe and reliable techniques for the inner portion of each CCHP system, between the CCHP systems and between the CCHP system and the active power distribution network, thereby realizing flexible economical scheduling and ensuring safety operation of a power grid.
Description
technical field [0001] The invention relates to a method for coordinating and dispatching a combined cooling, heating and power supply system under the environment of an active distribution network, and belongs to the field of optimal dispatching of an active distribution network. Background technique [0002] With the continuous development of the global economy, the gradual increase of the energy crisis and the increasingly severe air pollution, clean energy and renewable energy have received great attention. Many countries have formulated carbon emission standards with the aim of reducing energy consumption, improving power generation efficiency, reducing greenhouse gas emissions and encouraging the development of clean energy. Although conventional ore energy power generation technology is mature, with large single-unit capacity and high operational stability, its further development is restricted by shortcomings such as low energy utilization efficiency, poor peak-shavi...
