A kind of distributed electrical source power supply system and method for supplying power to
Technical field
The invention belongs to distributed energy technical fields, and in particular to a kind of distributed electrical source power supply system and supplier of electricity Method.
Background technology
In recent years, with the continuous expansion of city size, the infrastructure in city continues to increase input, and all trades and professions are all The booming impetus is showed, ever-increasing simultaneously in electricity consumption, the stability of power supply needs further raising, the world Property energy crisis also expedited the emergence of demand of the power industry to new energy, with the enhancing of user's environmental consciousness, and to electric power supply Answering reliability and economy, more stringent requirements are proposed, becomes electric power based on the distributed generation technology that new energy development utilizes An industrial new research hotspot.The combination of distributed power generation and bulk power grid mainly becomes what is developed as Future Power System Gesture;With centralized power generation, long distance power transmission and bulk power grid interconnect electric system for main feature be at present in the world power generation, The major way of conveying and distribution.The big system burden of this centralization the electrical energy demands of most users in the world, but It is that some drawbacks of its own are also increasingly presented:
1. technical sophistication, security and stability is insufficient.Accidental failure may cause power failure and entire power grid on a large scale Collapse;
2. with the growth of load, the power grid of this centralization cannot flexibly track in peak load period meets load need It asks;
3. environmental problem exposed day by day.
In recent years, worldwide energy crisis is increasingly presented, with coal-fired, nuclear power economic cost and Environmental costs Be continuously increased and requirement of the user to supply of electric power reliability is continuously improved, the distribution utilized based on new energy development Generation technology can reduce environmental pollution with it, reduce user terminal expense, while having both the advantages such as high efficiency and flexibility, more It is more taken seriously, there is bright development prospect in sustainable development.Since late 1980s, world power Industry is just experiencing from concentration supply power pattern to collection and is neutralizing the trend that the powering mode that dispersed phase combines develops.According to west state The experience of family:Bulk power system and distributed generation system are combined, useful supplement of the distributed generation technology as bulk power grid, It is to reduce investment outlay, reduces energy consumption, improves the important method of security of system and flexibility, and will be as the hair of the following generation technology Exhibition trend.
A kind of method for managing power supply and distributed apparatus of distributed apparatus are disclosed in 102147649 B of CN, wherein Method includes:When new subcard is inserted into the distributed apparatus, postpone providing power supply for the new subcard, it is new that mainboard obtains this Subcard type identification;The power information that the new subcard needs is obtained by the type identification;When entire distribution When the still not used power of formula equipment is less than the power that the new subcard needs, preferentially meet excellent in distributed apparatus The power supply requirement of the first higher subcard of grade, but it is still allocated without solving the problems, such as flexibly to use in above-mentioned 3 points.
Invention content
The technical problem to be solved by the present invention is to be directed in the prior art, in distributed power supply management in the prior art The phenomenon that there are flexibility ratios is not high, stability is poor, the energy insufficient utilization, point that the intelligence degree of proposition is high, stability is good Cloth power supply system and method for supplying power to.
