Facility to network load balance and peak load shifting effect application field.
Background technology
In recent years, the raising with living standards of the people and the rapid growth of electric load, network load peak-valley difference is progressively
Increase, at the same time, randomness, fluctuation, the regenerative resource large-scale grid connection of non-scheduling cause the peak regulation of power network to be asked
Topic is more protruded, and also causes a series of difficulty to power scheduling.Power supply and equipment for power transmission and distribution are according to power network in power system
Peak load planning construction, but the peak load of grid duration is shorter, cause for meet peak load demand and planning construction
Power equipment asset utilization ratio it is relatively low.It is power grid construction at this stage to research and solve peak load regulation network problem, improve asset utilization ratio
The important topic faced.
The power supply architecture of China is based on thermoelectricity, and most conventional fired power generating unit being capable of the scarce capacity exerted oneself of flexible modulation
The 50% of rated capacity, when load peak-valley difference is less than the adjusting range of fired power generating unit, it is necessary to part small-load generators start and stop peak regulation
Or banking fire peak regulation, or even need the more units of investment construction and improve the method for operation of fired power generating unit to meet peak regulation demand, from
And it is added significantly to the operating cost of system.According to statistics, the peak-valley difference of China in Recent Years network load is 38%~48%, with Liaoning
Exemplified by power network, Liaoning electric power grid peak load in 2011 is 22362MW, and low ebb load is 12708MW, and peak-valley difference is 43.2%.Peak regulation
Problem is the basic problem in operation of power networks.Start and stop are rapid, the flexible peak regulation technique of the method for operation meets peak load regulation network technology
Application demand.In the conventional peak regulation technique of power system, compared to fired power generating unit, Hydropower Unit start and stop are rapid, the method for operation is clever
It is living, and peak regulation depth is close to 100%, but the construction of Hydropower Unit is limited by geographical conditions, it is impossible to and carrying out large-scale promote should
With.
Extensive battery energy storage system, can be in the low power consumption phase with superior peaking performance because of its fast response characteristic

Reduction plans peak-valley difference, and its construction do not limited by geographical conditions.With lithium ion battery, vanadium redox battery, sodium
Sulphur battery is the battery energy storage system of representative, can effectively delay or even reduce power supply and power grid construction, improve efficiency of energy utilization
Level is utilized with power network total assets, changes the construction mode of existing power system.
Influence energy storage technology mainly includes energy-storage system scale, technology water in the principal element that power domain scale is applied
Flat, security and economy.When the capacity of energy-storage system reaches MW/MWh grades of scale abilities, the safety met under MW/MWh grades
Property, cycle life reach 5000 times and when the above, efficiency for charge-discharge reach 80% and the above that the high cost of energy-storage system turns into limit
Make the key factor of its large-scale application.
The Chinese invention patent of number of patent application 201510615651.6 discloses a kind of implicit based on unified electricity market
The virtual plant Optimization Scheduling of battery, belongs to the energy-optimised research field of power distribution network.It only analyzes electric power storage from algorithm
