Description
Technical field
The present invention relates to electric power resource optimization distribution field, especially a kind of automatic demand based on flexible load control is rung
Answer operational mode.
Background technology
With the structural adjustment of national economy, the per day peak-valley difference of network load and seasonal peaks and troughs difference expand day by day,
The adjustable standby resources capacity of power network is more and more limited, and administrative power cuts to limit consumption scene is still extremely serious.Load kind simultaneously
A large amount of accesses of the increasingly various and distributed power source, electric automobile of class feature, the peak load fluctuation to power network are brought
Bigger influence.Therefore demand response must be implemented, effectively alleviates supply of electric power peak value shortage phenomenon, further improve power network money
The utilization ratio of production, delay the investment of power equipment.
In March, 2015, State Council of the Central Committee of the Communist Party of China issue《Some opinions on further in-depth power system reform
(middle hair [2015] 9) text》, and the Ministry of Finance of National Development and Reform Commission on April 7th, 2015《On improving power emergency mechanism
Carry out the notice of the city integrated pilot work of demand Side Management》, it is proposed that strengthening mechanism is innovated, and implements demand response, note
The requirement of capacity building again, by implementing dsm, promote the effectively optimizing of electric power resource to configure, promote the section of the whole society
Can emission reduction.
From the point of view of load uses characteristic, electric load can be divided into rigid load, transferable load and can cut down negative
The class of lotus three, wherein rigid load is not influenceed by electricity price or incentive mechanism, such as administration's electricity consumption, hospital's base lighting, refrigeration, system
Hot electricity consumption etc., transferable load refer to electricity consumption behavior being transferred to the negative of electricity price relatively low other moment at the time of higher from electricity price
Lotus, but the electricity consumption behavior and power consumption can still occur, such as plant produced electricity consumption, resident's laundry electricity consumption, electric automobile (charging)
Deng, can reduction plans there is larger flexibility, when it thinks electricity price too high (being more than critical psychological price) i.e. reduce until
Cancel electricity consumption behavior, but also do not continue the electricity consumption behavior in the other period, such as：Air conditioning electricity, electric consumption on lighting etc..From Generation Side
Consider in the lump with Demand-side, load concept can be expanded, the distributed power source positioned at Demand-side is when it generates electricity, it is believed that demand
Side total load is reduced, and is regarded as " negative " load, has larger controllability.In summary, flexible load may include to turn
Move load, can reduction plans and the type load of distributed power source three, such as distributed power source, electric automobile, air-conditioning system, illuminator
Deng.
But simultaneously we it also seen that, domestic dsm especially demand response is still at an early stage, not yet builds
Rational electricity price or incentive mechanism are erected, dsm is more to rely on administrative means, and load management means are relative
It is single.For traditional rigid load control manner mainly for rigid load, control mode is simply extensive, have impact on dsm
Fair and just property, power consumer is actively engaged in the automaticity of network load adjustment and enthusiasm is also high, user participates in
Degree is low.
