Description
Technical field
The present invention relates to intelligent grid field, a kind of demand response system towards industrial undertaking and side
Method.
Background technology
Electric power is the pillar of modern industrial society, supports national economy and develops constantly at a high speed.In recent years, China is a lot
There is short of electricity phenomenon in area, and this " severe power shortage " phenomenon, it is not merely that supply of electric power deficiency is caused, but power supply and demand
Imbalance problem.Power supply and demand imbalance influences whether the sustainable development of China's electric power energy and stablizing of economic society.For
Alleviate this problem, the most domestic generally carry out Demand Side Response this effective regulating measure, by price signal with swash
The mechanism of encouraging guides power consumer to take rational electricity consumption behavior and power mode, such as, improve terminal power consumption efficiency and peak load transfer
Deng.The finished form of Demand Side Response is Spot Price, and the replacement scheme of Spot Price can be classified as 2 big classes: one is from fixing
Electricity price is to the various price between Spot Price, including tou power price；Two " the negative load schemes " being known as, typically
It is all based on, at special time, consumer is reduced consumption and payment is provided, including interruptible load, optional contract and Demand-side
Submit a tender.Demand Side Response can promote power supply and demand balance, safeguards system safe and reliable operation, stablizes improving electricity market
Property and operational efficiency important in inhibiting.
In July, 2012, the Ministry of Finance and National Development and Reform Committee combine issue " the city integrated pilot work of demand Side Management refer to
Lead suggestion ", specify that the incentive measure reducing electric load, just indicate the city integrated pilot work of demand Side Management
Formula starts to be implemented.Domestic scholars, also to demanding party's response and system and application, has carried out the discussion in theoretical and measure and research.
Industrial user has the features such as electric power consumption is big, and load adjustment is very fast, round-the-clock electricity consumption, is the important master participating in demanding party's response
Body.But, at present in the research field of intelligent grid, the management of various demand responses is only limitted to single area or resident mostly
User, lacks the demand response to industrial user and studies, and the system and method for the electricity consumption planning towards industrial undertaking.Simultaneously

Step 6.1, whether accept demand response project application notice according to industrial undertaking, and industrial undertaking agreed to
Electric power reduction, in conjunction with power project reduction, determine industrial undertaking's final electric power reduction.
Step 6.2, combine industrial enterprise power utilization load curve and highly energy-consuming equipment load curve per hour, peak of power consumption
Phase, low power consumption phase and electricity price are preferential, formulate and implement time-of-use price strategy.Reduce highly energy-consuming in the peak of power consumption period to set
Standby running power or make highly energy-consuming equipment keep constant power operation, thus reduce Power Consumption of Industrial Enterprises amount；
In the present embodiment, the beginning and ending time of peak of power consumption period, Peak-valley TOU power price and the maximum of peak of power consumption period permit
Being permitted natural law is all to be determined by electric company.Electrically-based demand tracing, it can be deduced that t period after Peak-valley TOU power price
Power consumption.Grid company carries out power supply according to estimated power consumption, and industrial undertaking makes full use of limited electricity consumption
Peak period, natural law, selected the suitable rush day based on principle of profit maximization, reduced electric load, with maximum overall
Benefit.
Step 6.3, combine business electrical load curve and peak times of power consumption, formulate Interrupted load management strategy.Can interrupt
Period interrupts Power Consumption of Industrial Enterprises, by interrupting the expenditure minimizing of period demand charge and the electricity price discount in other periods
And earn a profit；
The outage cod of industrial user and advance notification times, interruption duration, power failure time of origin are relevant, this enforcement
In example, advance notification times is defined as 1 hour；Interruption duration calculates by the hour, and power off time occurred in peak times of power consumption,
Determined by grid company.Outage cod load rejection electricity is quadratic function relation.Enterprise benefits equal to by interrupting the period
Demand charge is paid minimizing and the electricity price discount in other periods and is earned a profit and deduct the outage cod of industrial user.
Step 6.4, combine each highly energy-consuming equipment different capacity table duration of runs and repair time planning chart, formulate power consumption and set
For adjustable strategies maintenance time.Adjust the energy consumption equipment repair time, by originally at the equipment of low power consumption period maintenance, be adjusted to
The peak of power consumption period keeps in repair；
