Description

Consider the source lotus coordinated operation dispatching method of Multiple Time Scales polymorphic type demand response
Technical field
The invention belongs to distributed power source and flexible load coordinated operation Research on Scheduling field, more particularly, to A kind of source lotus coordinated operation dispatching method for considering Multiple Time Scales polymorphic type demand response.
Background technology
In recent years, with renewable energy power generation equipment update and regenerative resource interconnection technology increasingly into Ripe, the regenerative resource using wind-powered electricity generation, photovoltaic as representative is quickly grown in the world.But compared with conventional power source, due to Wind-powered electricity generation, photovoltaic unit output are influenceed by the randomness of natural cause (wind speed, light intensity etc.), and stronger intermittence, randomness is presented And the features such as fluctuation.When wind-powered electricity generation, grid-connected permeability reach to a certain degree, wind-powered electricity generation, the online capacity of photovoltaic are for hair Electricity plan work out, active Real-Time Scheduling and FREQUENCY CONTROL and spare capacity arrangement etc. will all produce extreme influence.If no Effectively scheduling can be realized, will necessarily occur it is unnecessary abandon wind, abandon light, influence the economy of operation of power networks, can also shadow when serious Ring power network safety operation.Demand response (Demand Response, DR) participates in electric network active scheduling, for consumption wind-powered electricity generation, light The uncertainty of volt provides a kind of new method.By calling Demand-side resource, user is set to be carried out with Utilities Electric Co. interactive, can To make Demand-side resource participate in the scheduling of power system as calling Generation Side resource.Therefore, power distribution network is studied Lotus coordinated operation strategy in source turns into one of study hotspot of current generation power industry development.
Scheduling of the current scheduling strategy for demand response resource focuses mostly on dispatches a few days ago, more time chis of demand response Degree characteristic does not obtain enough attention always.It is various to participate in the load species of demand response, for classification above, it is negative both to have included industry Lotus, include resident load again.Not only motor type load had been included but also including the temperature control load such as refrigerator, water heater.These loads participate in adjusting The potentiality of degree and the pattern of response are all otherwise varied.In summary, on the one hand the precision of scene prediction is relevant with time scale, when Between yardstick it is shorter and nearer apart from current time, then precision of prediction is higher;On the other hand, the various resources for participating in scheduling are deposited in itself In the characteristic of Multiple Time Scales, individually it is difficult to make full use of the Multiple Time Scales of demand response resource special using scheduling model a few days ago Property, all kinds of resources are carried out with economic scheduling.Therefore, it is necessary to a kind of new in terms of the lotus coordinated operation strategy study of power distribution network source Method improve existing scheduling strategy.Based on above-mentioned consideration, the present invention proposes one kind based on " multilevel coordination, refining step by step " The source lotus coordinated operation strategy of Multiple Time Scales polymorphic type demand response, it can effectively cause different types of demand response resource Electric power system dispatching is played an active part in, realizes the scheduling that becomes more meticulous, improves power distribution network economic benefit and environmental benefit.
