Run the calculation method of spare response quautity.
Background technique
Traditional operation is spare to refer to that generating set can provide certain power generation within the short time (10 minutes)
Power output, cope with system loading fly up or the contingent of certain units.
However, the development of current electric system faces some new challenges, such as peak-valley difference sustainable growth, extra-high crimping
Enter, renewable energy power generation ratio is continuously improved.To cope with these challenges, electric system needs higher operation reserve capacity,
To guarantee the safe and reliable of system.The spare rising that will lead to system operation cost of operation of higher capacity and using energy source
It is inefficient.
When imbalance occur in electric system power generation and electricity consumption, and workload demand is greater than generating set power output, two methods can
It is balanced with recovery system, one is to increase unit output, the other is reducing load consumption.Air conditioner load occupies weight in load
Ratio is wanted, is one of the critical load for participating in demand response.The standby or temperature of air conditioner load adjusts, and can be equivalent to generator
The power output of group increases.
It therefore, is considered as the effective ways for solving above-mentioned challenge using the demand response that air-conditioning is participated in as the load of representative.
However, the spare research of the operation for how quantifying demand response offer is very few, the operation for hindering demand response offer is spare really
Participate in the operation of system.
Summary of the invention
For the problems in above-mentioned background technology, it polymerize the present invention provides a kind of air-conditioning and electric power system operation standby is provided

Wherein, RC is response capacity, and α is fluctuation scale parameter, and RT is the response time.
The safe and reliable operation of electric system of the present invention needs generating set offer operation spare, to cope with the load of system
Fluctuation or generating set accident.When there is imbalance in electric system power generation and electricity consumption, and workload demand is greater than generating set power output,
Two methods can be balanced with recovery system, and one is to increase unit output, the other is reducing load consumption.Air-conditioning is as a kind of
Common load, occupies important proportion in power system load, and air-conditioner standby can reduce system loading, be equivalent to generating set
Increase generated output, and the standby or temperature adjustment of air-conditioning short time is smaller on the normal life of resident influence.Meter of the present invention
Calculating four parameters of acquisition can be used for polymerizeing air-conditioning the Opportunity awaiting control for linear for providing electric power system operation standby to reduce electricity consumption, and control is used
Electricity.
