Multi-building micro-network model prediction and control method based on non-cooperative game

Abstract

The invention relates to a multi-floor micro-building model prediction and control method based on a non-cooperative game. According to the technical schemes, the multi-building micro-network model prediction and control method is characterized in comprising the following steps that firstly, a non-cooperative game model of multi-floor micro-network is established; secondly, a multi-micro network model prediction and regulation model based on the non-cooperative game is established; thirdly, interior power optimization is conducted based on prediction data obtained through step 2 to obtain thesurplus electricity of each time in the prediction time domain, a game is conducted by all buildings with own benefits as the biggest principle, and thus the trading power and electrovalence of all buildings and distribution network and other buildings; and fourthly, the optimized control sequence of all building micro networks in a control time domain is obtained through a model prediction and the non-cooperative game, and the optimized control sequence comprises call wire power of the distribution network, trading electric quantity with other micro-network, electrovalence and refrigerating capacity, and then the first control sequence is issued to all building micro networks. According to the multi-floor micro-building model prediction and control method based on the non-cooperative game, electricity selling benefits of all buildings can be improved, and the operation cost of the buildings can be further lowered.

Description

technical field [0001] The invention belongs to the technical field of optimal control of new energy and renewable energy, and relates to a multi-building micro-grid model prediction and control method, in particular to a non-cooperative game-based multi-building micro-grid model prediction and control method. Background technique [0002] With the acceleration of urbanization and the improvement of people's living standards, my country's energy demand is growing rapidly, and building energy consumption is expected to account for 35% of the country's total energy consumption by 2020. In recent years, more and more distributed energy supply systems have been integrated on the building side. Buildings have changed from energy consumers to energy producers and consumers, and have the ability to trade energy. The micro-grid system with buildings as the main body can provide a transaction platform and management method for transactions between buildings. Power trading between bu...

Problems solved by technology

[0005]However, the game strategy proposed in the above research has the following problems: (1) The non-cooperative game competition problem of the traditional multi-microgrid system adopts the general Nash optimization iterative method, and there is It takes a long time to solve the problem; (2) Most of the research focuses on the game process between the electricity seller or the electricity buyer or the two parties with a fixed relationship. However, in the multi-building microgrid system, at different times The role of the game party will change between the power seller and the power purchaser; (3) The cost of distribution network service is not considered or set as a fixed value
