| With the increasing number of distributed renewable energy connected to the grid and the increasing power fluctuation of the grid,adjusting the power balance through generation side resources cannot meet the needs of power system operation.Therefore,the utilization of demand-side resources to absorb renewable energy will receive more and more attention.The air conditioner is a flexible load with a certain heat storage capacity.As an excellent demand response resource,air-conditioning load has great potential.Reasonable load control can better guarantee the comfort of residents.Therefore,this paper takes air conditioning load as the research object to study its modeling method,and studies the control strategy of air conditioning participating in demand response.This paper mainly carries out the following work:Firstly,in order to solve the difficulty of centralized control to meet the Plug and Play requirements of distributed devices,this paper abstracts the system formed by the connection of air-conditioning load controllers as a multi-agent network,which realizes the task solution through the information interaction between two agents.The consistency algorithm used for multi-agent coordination is analyzed,and its algorithm model and formula are summarized.Secondly,by analyzing the equivalent thermal parameter model of air conditioning load,this paper establishes the load compensation cost function of load aggregator for power users.Reference such as consumption of principle will air conditioning load Incremental Cost rate as a variable,consistency in consistency algorithm research based on air conditioning load Incremental Cost master-slave consistency model,on the basis of considering constraint conditions,finally realizes the large-scale power optimal distribution of air conditioning load system,ensure the economic operation of the system.Finally,based on the master-slave consistency model of air conditioning load increment cost,an improved multi-agent consistency algorithm considering the thermodynamic characteristics of the whole process of air conditioning is proposed.Taking into account the reduction and recovery process of air conditioning load,the air conditioning load can be restored to the initial set temperature in a short time,improving the comfort of users,and ensuring the economic efficiency of regulation while fast and accurate control. |
