Description

A kind of air-conditioning polymerization provides the computational methods of electric power system operation standby response quautity
Technical field
The present invention relates to a kind of power grid control amount computational methods, a kind of more particularly to air-conditioning polymerization provides power system Run the computational methods of standby response quautity.
Background technology
Traditional operation is standby to refer to that generating set can provide certain generating within the short time (10 minutes) Exert oneself, tackle system loading fly up or some units contingent.
However, the development of current power system faces some new challenges, such as peak-valley difference sustainable growth, extra-high crimping Enter, renewable energy power generation ratio is improved constantly.To tackle these challenges, power system needs higher operation reserve capacity, So as to ensure the safe and reliable of system.The standby rising that can cause system operation cost of operation of higher capacity and using energy source It is poorly efficient.
When imbalance occur in power system generating and electricity consumption, when workload demand is exerted oneself more than generating set, two methods can With recovery system balance, one is to increase unit output, and another is to reduce load consumption.Air conditioner load occupies weight in load Ratio is wanted, is one of critical load of participation demand response.The standby or temperature adjustment of air conditioner load, can be equivalent to generator The increase of exerting oneself of group.
Therefore, the demand response that the load with air-conditioning as representative is participated in is considered as the effective ways for solving above-mentioned challenge. However, the standby research of the operation for how quantifying demand response offer is very few, the operation for hindering demand response offer is standby real Participate in the operation of system.
The content of the invention
For the problem in above-mentioned background technology, the invention provides a kind of polymerization of air-conditioning provides electric power system operation standby The computational methods of response quautity, can be such that air-conditioning polymerization unifies with the operation Backup of generating set, be easy to instruct power system to need Ask the execution of response.
Air-conditioning polymerization provides electric power system operation standby response quautity includes response capacity, response time, duration, climbing Four parameters of rate, technical scheme is specifically calculated using following steps：
1) the air-conditioning aggregate power PWR before according to demand response signal sendsmaxWith the minimum reached after execution demand response Power P WRminSubtracted each other using below equation, calculate and obtain response capacity RC；
RC=PWRmax-PWRmin
Wherein, RC is response capacity, PWRmaxAir-conditioning aggregate power before sending for demand response signal, PWRminTo perform The minimum power reached after demand response；
2) the lasting response for calculating acquisition air-conditioning polymerization offer electric power system operation standby response according to response capacity RC is opened Time beginning tdsPersistently respond end time tde, and according to persistently response time started tdsCalculate and obtain response time RT；
3) according to persistently response end time tdePersistently respond time started tdsCalculate and air-conditioning polymerization offer electric power is provided The duration DT of the standby response of system operation, calculates acquisition air-conditioning polymerization offer Operation of Electric Systems standby according to response time RT With climbing rate RR of response.
The step 2) in lasting response end time tde, persistently respond time started tdsIt is concrete with response time RT Calculated using below equation：
2.1) air conditioner load power curve PWR (t) known to calculates two solutions obtained on curve using below equation：
PWR (t)=PWRmax- RC (1- α %)
Wherein, PWRmaxAir-conditioning aggregate power before sending for demand response signal, RC is response capacity, and α is fluctuation ratio Parameter；
2.2) above-mentioned two solution respectively persistently responds end time tde, persistently respond time started tds, meet tds,tde (tds≤tde)；
2.3) again response time RT is calculated using below equation：
RT=tds-tsig
Wherein, tsigFor demand response signal sending time.
The step 3) in duration DT using below equation calculate obtain：
DT=tde-tds。
The step 3) in climbing rate RR using below equation calculate obtain：
RR=RC (1- α %)/RT
Wherein, RC is response capacity, and α is fluctuation scale parameter, and RT is the response time.
The safe and reliable operation of power system of the present invention needs generating set offer operation standby, to tackle the load of system Fluctuation or generating set accident.When imbalance occur in power system generating and electricity consumption, when workload demand is exerted oneself more than generating set, Two methods can be balanced with recovery system, and one is to increase unit output, and another is to reduce load consumption.Air-conditioning is used as one kind 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 normal life of the standby or temperature adjustment of air-conditioning short time on resident affects less.Present invention meter Calculate four parameters of acquisition and can be used to be polymerized air-conditioning the Opportunity awaiting control for linear that electric power system operation standby is provided to reduce electricity consumption, control is used Electricity.
The invention has the advantages that：
The present invention can be such that air-conditioning polymerization unifies with the operation Backup of generating set, be easy to instruct power system demand to ring The execution answered, reduces electricity consumption, controls power consumption.
