Embodiment Construction

[0025] A multi-agent-based microgrid operation control method, using electricity price as the main reference index for microgrid operation, abstracting renewable energy power generation devices, loads, steam turbines, batteries, and controllers in the microgrid into multiple agents , so as to constitute a decentralized multi-agent system. In the multi-agent system, the load agent acts as a consumer or buyer, the renewable energy generation device agent and steam turbine agent act as a producer or seller, and the battery agent Playing the role of producer, seller or buyer, the controller multi-agent plays the role of pricer, that is, the controller decides the peak and valley electricity price and whether to purchase or sell electricity to the backbone network. Based on the electricity price, operating cost and load demand, each agent Adjustment is made through negotiation, so as to realize the intelligent operation of the microgrid.

[0026] The load agent plays the role of co...

Abstract

The invention discloses a micro-grid operational control method based on multiple agents. The electricity price serves as the main reference index of micro-grid operation, a renewable energy power generation device, a load, a turbine, a battery, a controller and the like in a micro-grid are abstracted into the multiple agents respectively, and therefore a dispersed multi-agent system is formed. In the system, the load agent plays a role of a consumer or a buyer, the renewable energy power generation device agent and the turbine agent play a role of a producer or a seller, the battery agent plays a role of a prosumer or a buyer and seller, the controller agent plays a role of a price maker, and peak and valley prices and whether electricity is bought from or sold to a main grid or not are determined by the controller. Based on the requirements for electricity prices, operating cost and the load, adjustment is conducted on all the agents through negotiation between the agents, and therefore intelligent operation of the micro-grid is achieved.

Description

technical field [0001] The invention relates to the field of power data systems, in particular to a multi-agent-based micro-grid operation control method. Background technique [0002] With the development of the national economy, the demand for electricity continues to grow rapidly, and the main construction is concentrated on large-scale centralized power sources such as thermal power, hydropower, and nuclear power plants, as well as ultra-high voltage long-distance transmission grids. However, as the scale of the power grid continues to increase, the disadvantages of the ultra-large-scale power system are increasingly revealed, such as high cost, difficult operation, and difficulty in adapting to the increasingly high security and reliability requirements of users and the changing power supply demand. Especially in recent years, large-scale large-scale power outages have occurred, highlighting the vulnerability of traditional large power grids, mainly in the following asp...
