Problems solved by technology
[0003] At present, there are few related studies on multi-mode switching control of hybrid energy generation system. The research team of the inventor of this patent has previously proposed an event-triggered multi-mode coordinated switching control based on multi-agents for microgrid [[1] Chun-xiaDou ,BinLiu,JosepM.Guerrero,Event-triggeredhybridcontrolbasedonmulti-agentsystemformicrogrids,IETGeneration,Transmission&Distribution,8(12):1987-1997,2014], but in this study, when constructing the event-triggered switching strategy, the modal switching time, Switching interval and switching times, which can easily cause an event to trigger simultaneous switching of several distributed generation units, or even trigger switching continuously. It takes a certain execution time and also needs a certain interval

The invention provides a multi-mode coordination switching control method of a hybrid energy power generation system. Based on a two-layer distributed coordination control intelligent agent, event trigger multi-mode coordination switching control with higher reasonability and intelligence is constructed, so that the hybrid energy power generation system can intelligently switch modes inside each distributed power generation unit and switch the modes inside each distributed power generation unit in a coordination manner when facing natural condition change and greater load fluctuation, and renewable energy power generation is utilized as much as possible while the maintenance hinge node voltage is in a safe range, so that low-carbon economical efficiency of electric power supply is guaranteed.
Description
technical field [0001] The invention belongs to the field of smart grid control, and in particular relates to a multi-mode coordinated switching control method for a hybrid energy generation system. Background technique [0002] As the lifeline industry of energy in modern society, electric power plays an important role in energy conservation, emission reduction and sustainable utilization of energy. Relying on information technology, adopting distributed power generation technology, making full use of clean and renewable energy, building a hybrid energy power generation system, and maximizing energy and environmental benefits are the main means for the power industry to achieve a low-carbon economy. In order to achieve the goal of safety, reliability and low-carbon economy, the hybrid energy power generation system needs to have the ability to "actively accept renewable energy power generation, optimize the allocation of multi-energy power generation, and intelligently mana...
