A kind of method that air conditioner load active control participates in power peak regulation
Technical field
A kind of the present invention relates to Demand Side Response control field, more particularly to air conditioner load master based on building thermal inertia The method that dynamic control participates in power peak regulation.
Background technology
In traditional sense, the control mode of electromotor is easier compared to the control mode of load, generally regarding power train System load is passive physical terminal, realizes power system active power using the control mode of generating follow load change Balance control, control object is all the time in mains side.However, the load variations of power system are to cause system active power uneven One of the main reasons.
With increasingly serious, the regenerative resource such as Devoting Major Efforts To Developing wind energy, solar energy of problem of environmental pollution, fossil energy is reduced The consumption and discharge in source, is the inexorable trend of China's energy development.With the further development of regenerative resource, conventional electric power system The electrification structure of system changes, and the high coal unit installed capacity proportion of coal consumption will decline to a great extent, and cleans without dirt The shared ratio in power system total installation of generating capacity of the installed capacity of the Renewable resource generating set such as the wind energy of dye and solar energy Example will be substantially increased.
There is great variety, the active balance control no longer office of the new period in the new period in the electrification structure of conventional electric power system It is limited to control the traditional control method of coal unit.Reason is as follows:On the one hand, in order to improve the operational efficiency of coal unit, and Reduce operating cost and reduce the discharge of pollutant, coal unit develops towards Large Copacity supercritical direction, therefore should reduce which Follow load changes and provides standby ratio;On the other hand, the randomness having due to regenerative resource and undulatory property feature, The anti-peak-shaving capability to a certain extent that especially wind-powered electricity generation also has, with the liter year by year of these regenerative resources installation ratios It is high so that the ability of power supply trace load variations declines, while the large-scale grid connection of regenerative resource causes to hold system reserve The requirement of amount is significantly improved.In sum, the traditional control method of the active balance of follow load change is adjusted by mains side Receive greatly challenge.
As the development of intelligent grid and communication network is perfect, the controllability of load is enhanced, established source and lotus The basis of control realization active balance is coordinated in side, and load is become and is actively engaged in active balance by traditional passive control Control.
With the growth of national economy, electricity needs is in line the situation of rising, supply of electric power often in tense situation, Huge challenge is brought to the control of power system active balance.Particularly extreme climate is frequently occurred in recent years so that air-conditioning makes Consumption increases year by year, and the sharp increase of air conditioner load has become summer network load characteristic and deteriorated the important original with power shortages Cause.For meeting the demand of ever-increasing air conditioner load, build the variable load plant of high cost or run into load peak simply To user using load management measures such as power cuts to limit consumption, these can not all meet the needs of form development.
The one kind of air conditioner load as temperature control load, can convert electrical energy into the heat energy being stored in room, the energy Conversion and the characteristic for storing cause air-conditioning to become the load of most demand response potentiality.In addition, the building enclosure of building has Good insulation effect, slowly, building has great thermal inertia for indoor and outdoor heat exchange.Therefore can utilize This thermal inertia of air-conditioning and building, in the load peak period, and on the premise of user's comfortableness is not affected, takes suitable Mode controls the start-stop time of air-conditioning, reduces air conditioner load peak.
