Abstract

The invention discloses a method for calculating an electric power system operation reserve response quantity provided by air-conditioner aggregation The electric power system operation reserve response quantity provided by air-conditioner aggregation comprises response capacity, response time, duration time and a ramp rate; the response capacity can be obtained after air-conditioner aggregation power which is reached prior to emission of demand response signals is subtracted from minimum power which is reached after demand response is executed, two times for electric power system operation reserve response provided by air-conditioner aggregation are calculated according to the response capacity, the response time and duration time can be further calculated and obtained, and the ramp rate of the electric power system operation reserve response provided by air-conditioner aggregation can be calculated and obtained according to the response time. The method disclosed in the invention can be used for quantifying operation reserve provided by air-conditioner aggregation, the operation reserve provided by air-conditioner aggregation is enabled to be consistent with operation reserve provided by a power generation machine group in terms of parameters, and electric power system demand response work can be carried out conveniently.

Description

technical field [0001] The invention relates to a calculation method of a power grid control quantity, in particular to a calculation method of an air conditioner aggregate to provide a standby response quantity for power system operation. Background technique [0002] Running standby in the traditional sense means that the generator set can provide a certain power generation output in a short period of time (10 minutes) to deal with a sudden increase in system load or accidental accidents of some units. [0003] However, the development of today's power system is facing some new challenges, such as the continuous increase of peak-to-valley difference, UHV access, and the increasing proportion of renewable energy power generation. In order to meet these challenges, the power system needs a higher operating reserve capacity, so as to ensure the safety and reliability of the system. A higher capacity running reserve will lead to an increase in system operating costs and ineff...
