Direct load control method and system for aggregating air conditioner demand response

Abstract

The invention discloses an aggregation air conditioner demand response direct load control method and system, and belongs to the field of power system demand response control. According to the invention, suppression of sudden load change is considered in the start-stop stage of demand response, a queuing method is adopted to control the start-stop time of the demand response of each air conditioner, and the start-stop time of the load demand response of each air conditioner is arranged in a staggered mode, so that the situation that loads instantly and collectively enter a refrigeration or standby state to cause a load peak is avoided; an aggregator can realize aggregation control a terminal air conditioners through an intelligent controller mounted on an air conditioner load terminal, so that the requirement of a final demand response expected target value is met; and load reduction is carried out by adopting a demand response control strategy meeting a load reduction target in a demand response middle period, the set temperature of each air conditioner is increased to a demand response set temperature from the initial set temperature, the operation state enters the standby state from the refrigeration state, and finally the total power of the aggregation air conditioner is reduced, so that the effect of reducing the load peak is achieved.

Description

technical field [0001] The invention belongs to the field of power system demand response control, and more specifically relates to a method and system for aggregated air conditioner demand response direct load control. Background technique [0002] With the continuous development of the power system, demand response plays an increasingly important role in balancing the supply and demand balance of the power grid and maintaining the safe and stable operation of the power grid. Demand response means that when the price of the wholesale electricity market rises or the reliability of the system is threatened, the electricity user changes its inherent habitual electricity consumption pattern after receiving the direct compensation notice from the power supply party to reduce the load or the signal of the electricity price rise. , to reduce or shift the power load in a certain period of time to respond to the power supply, thereby ensuring the stability of the power grid and inhi...

Problems solved by technology

However, in the implementation process of direct load control, if the set temperature of each air conditioner in the demand response period cannot be reasonably set, the expected demand response target cannot be achieved; if the start and end time of each air conditioner participating in demand response cannot be reasonably controlled, it will cause Each user adjusted the set temperature of the air conditioner in an orderly manner, causing a very high load rebound and causing a huge impact on the power grid
