Description

A kind of distributed power supply smart grid system of hierarchy structure
Technical field
The utility model relates to the intelligent grid technical field, is specifically related to a kind of distributed power supply smart grid system of hierarchy structure.
Technical background
Recently, intelligent grid one of develops as the national strategy of various countries, is subjected to pursuing of the whole world.Consulting available data can see, so-called " intelligent grid ", as its name suggests, be meant a kind of become clever novel power grid, understand more and obtain and electrical power distribution " wisdom ".The fusion of that distribute, integrated, high-speed bidirectional communication network and multi-source power node network distribution, interactive is the magic weapon of its " tower above the rest in vigour and height of intellect ".Under the devising strategies at the headquarters of its advanced sensing and measuring technique, equipment and technology, control method and DSS technology, reliable, safety, economy, efficient, environmental friendliness and intelligent grid safe in utilization have been made.
Intelligent grid will be allowed the access of various dissimilar generatings and energy-storage system, will impel electricity market flourish.Intelligent grid can be managed as parameters such as the energy, capacity, volume change rate, trend obstructions most effectively by the interaction of Supply and Demand on the market, reduces trend and blocks, and enlarges market, compiles more buyer and seller.
Intelligent grid is optimized its assets application, makes operation more efficient.For example, so that assets are brought into play its best ability, assets can be used by the dynamic evaluation technology under bigger load by continuously monitoring and estimate its ability.
Traditional electrical network being transformed into the intelligent grid of a new generation safety, efficient and environmental protection, and forming new technical industry, is the important channel that national economy makes the transition, and is considered the important motivity of reinventing economy and energy general layout.
The core of intelligent grid is to make up the intelligent network system of unified networking of the various energy resources that possesses intelligent decision and adaptive adjustment capability and distributed management, can monitor in real time and gather electrical network and user power utilization information, and adopt most economical and safest power transmission and distribution mode to give the terminal use with power delivery, realization improves the reliability and the efficiency of energy utilization of power grid operation to the allocation optimum and the utilization of electric energy.
The kind of distributed power source (DER) is a lot, comprises small power station, wind power generation, photo-voltaic power supply, fuel cell and energy storage device (as flywheel, ultracapacitor, the storage of superconduction magnetic energy, flow battery and sodium sulfur storage battery etc.).Because distributed power source (DER), be subjected to the influence of natural conditions as solar energy and wind power generation, electric energy output is discontinuous also extremely unstable, for addressing this problem, power plant must electric power storage and inversion send electric aspect the cost great amount of investment, and effect is also not ideal, cause no small waste, how how maximum the returns of investment of performance clean energy resource make unsettled power supply can satisfy the needs that people use, and is the problem that the whole world that clean energy resource effectively utilizes is paid close attention to.In general, its capacity of distributed power source (DER) is from 1kW to 10MW.Distributed power source in the power distribution network (DER) therefore is widely adopted owing near load center, reduced the needs to the electrical network expansion, and improved power supply reliability.Particularly help to alleviate the distribution type renewable energy of greenhouse effect, under the support energetically on many national government policies, increase rapidly.
A large amount of distributed power sources also moves on the net in middle pressure or low-voltage distribution; thoroughly change the characteristics of traditional unidirectional trend of distribution system, required system to use new protection scheme, voltage control, instrument and intelligentized more novel supply network to satisfy the needs of two-way trend.
The rosy prospect in the future of intelligent grid and its important strategic meaning just, global various countries greatly develop.Particularly the U.S. is present, and what intelligent grid research was comparatively ripe mainly is the U.S., and a plurality of states of the U.S. have begun to design the intelligent grid system, and electronic industry and information industry tap have all dropped into the intelligent grid business in the world.According to official's introduction in June, 2009 of USDOE China office, it is first intelligent grid city of the U.S. that the bohr of Colorado gets the city.Each household family has all arranged intelligent electric meter, and people can understand electricity price at that time very intuitively, thereby some things, is arranged in the low time period of electricity price such as wash clothes, pressing etc.Ammeter can also help people preferentially to use clean energy resourcies such as wind-powered electricity generation and solar energy.Simultaneously, transformer station can collect the electricity consumption situation of every household.In case have problem to occur, can be equipped with electric power again.The feature of this intelligent grid technology mainly is, each household family has all arranged intelligent electric meter, and people can understand electricity price at that time very intuitively and adjust the electricity consumption plan, and simultaneously, ammeter can also help people preferentially to use clean energy resourcies such as wind-powered electricity generation and solar energy.
