Description
Technical field
The present invention relates to dispatching of power netwoks field, especially a kind of virtual regulating units based on automatic demand response
Dispatching method.
Background technology
By years development, China's dispatching of power netwoks has achieved tremendous development, establishes highly reliable with one
Basic platform and " monitoring in real time and early warning, management and running, operation plan, Security Checking " four major class applications
The dispatch automated system of composition, realize reliable scheduling and management to power network, strong guarantee power network fortune
Capable security and economy.Because power supply with demand must keep balancing in good time, therefore must in system
Certain spare capacity must be left, avoids causing surely when generating set forced outage, negative rules fluctuation
Qualitative destruction, the configuration of spinning reserve are the major issues for needing to consider in a dispatching of power netwoks operation.
The problem of configuration of spinning reserve is substantially system operation reliability and economy integrated decision-making, works as system
When possessing higher spinning reserve capacity, reliability is higher, but economy is poor；The on the contrary then reliability of system
Difference and good economy performance.At present, dispatching of power netwoks is conceived to safety and reliability premise more, according to《Power system skill
Art directive/guide》Regulation, to ensure the demand of spare capacity and acquisition, its stand by margin is generally the one of load
Certainty ratio, such as 10%-20% or equal to system maximum single-machine capacity, reliability basic guarantee, economy deficiency.
Dsm provides the different another thinking of more traditional dispatching of power netwoks " generating follows load ",
The burdened resource of user side is transferred, actively adjusts power network peak-valley difference.The Central Committee of the Communist Party of China in 2015, State Council's hair
Cloth《Some opinions on further in-depth power system reform》(No. 9 texts), it is indicated that " further lifting with
Equilibrium of supply and demand safeguard level based on dsm.Relevant government department will according to the marketization direction, from
Demand-side and the aspect of supply side two are started with, and do quantity of electricity whole machine balancing well.The safety for improving supply of electric power can
By level." but up to the present, due to the huge uncertainty of load responding, there is no method by the active of load,
Quick regulation lifting, with level, is carried out orderly to the standby level of dispatching of power netwoks real time rotation to load
The fast dispatch method of combination.
