Property evaluation system and method.
Background technique
In modern and following power distribution network, a large amount of generation of electricity by new energy form accesses extensively, and electric car etc. is new
A large amount of appearance of type load, so that the uncertain factor that power distribution network is faced is more complicated, this just needs distribution system to have
Stronger elasticity ensures the safe and reliable and economical operation of distribution system to cope with the influence and impact of these uncertain factors,
And new energy is received as far as possible.In addition, medium voltage distribution network may also be subjected to the destruction and influence of natural calamity, such as cruelly
Rain, typhoon, thunder and lightning and ice damage etc. also require power distribution system from the angle for ensureing that load, particularly important load are powered
System has certain elasticity.
Distribution system includes the different link such as power supply, power grid, load and energy storage.Power supply therein is mainly new energy,
The power supply of the forms such as wind-powered electricity generation, photovoltaic power generation.Therefore, distribution system and power distribution network have certain difference, including power distribution network.
Traditional evaluation method and index for intermediate distribution system mainly include safety (N-1), reliability
Several aspects such as (SAIDI, SAIFI etc.) and economy (network loss, cost of investment), respectively from different sides to medium-voltage distribution
System is evaluated.And it is less for the research of the photoelastic evaluation of intermediate distribution system, relative to traditional intermediate distribution system
Evaluation index and method, photoelastic evaluation are the evaluation index and method of a kind of synthesis.The concept of elastic (resilience) is earliest
Originating from field of ecology, it is widely used in the ability that evaluation system bears fast quick-recovery after external disturbance and disturbance later.
Flexible power refers to that the responding ability of objective uncertain factor variation is coped in electric system.Currently, being studied for flexible power
Most is loading elasticity.According to the objective uncertain factor of difference for influencing load variations, loading elasticity can be there are many class
Type, what domestic and international research range was most wide at present is price elasticity.The price elasticity of load is primarily referred to as depositing between load and electricity price
In resilient relationship, takes the form of load and change with the variation of price.Other than the price elasticity of load, duration of load application
Elasticity concept it is also critically important (" coordinated control of the Operation of Electric Systems reliability in electricity market based on Price elasticity ", in
State's electrical engineering journal, 2005,25 (24): 34-40；" tou power price under across period demand-price elasticity ", relay,
2006,34 (21): 68).The time elasticity of load refers to resilient relationship existing for load and time, but does not imply that load at any time
Between Variation Features, but emphasize the transferability of load at any time, i.e., load is transferred to another time from a period
A possibility that section.But the price elasticity of load and time elasticity are complementary.The time elasticity of load often through
What price guidance or the mode of economic compensation were realized, and embodied by way of price elasticity.Common practice
It is to formulate different electricity prices for different periods, load will be caused to shift, is i.e. the time elasticity of realization load.Therefore, exist
Demand-price elasticity and time elasticity on the basis of this are consistent.
It is then relatively fewer for the otherwise elasticity research in addition to loading elasticity at present.
