The Design And Implementation Of Demonstration System For Distributed New Energy Storage System

Distributed Micro-grid Storage System was researched and developed successfullyby Engineering Research Center Of China for advanced energy-storage materials in July2010, which filled the blank for new energy-storage system in the field of new energytechnology in China. Because the Distributed Micro-grid Storage System has just beencompleted, a lot of people do not know much about its structure and operation principle.With the development of society, the national grid not only needs to meet the growingdemand for power resources, but also to meet the power needs of our diversity. In the pastfew decades, our country continues to expand the scale of the national grids and it hasgradually developed into a centralized power generation, large network of long-distancetransmission system. Coal-based power structure, not only lack the ability to regulate, butincreasingly serious pollution of the environment. Therefore, based on distributedgeneration of new energy sources are more and more popular.Compared to the national grid, distributed power exhibits intermittent and randomcharacteristics. The power can rely on their own ability to regulate to meet the power loadbalancing, and does not control, with other energy storage devices need to provide support.A variety of non-scheduling of distributed power to rely on traditional centralized powersystem operation scheduling personnel management brought new difficulties. The lack ofeffective management will result in run-time distributed power "randomness" to the powersecurity.In order to solve the above problems, make distributed power to the system and theuser benefits of electricity to more fully play out, the researchers proposed the concept of"micro network". Distributed network is defined by the micro-power energy storagedevice, the energy conversion device, and monitoring a load associated protective devicemade of small fat distribution and collection system. It is a realization of self-control, protection and autonomous systems management. It can run with the big power grid andcan also be run in isolation. ractice has proved that the distributed generation micro-gridenergy storage is a fully capable system is the most effective way for distributedgeneration.The demonstration software of the Distributed Micro-grid Storage System show usPhotovoltaic Subsystem and Wind Power Subsystem and Battery Energy Storage Systemof Distributed micro-grid storage system will how to work in the different environmentalconditions and the relationship between those subsystems and State Grid Corporation ofChina and power consumers dynamically. The whole demonstration system is divided intothree levels: the interface-showing layer, function layer and data-storage layer. A basicdemo interface was built by using MFC Framework. The Several basic structures ofDistributed micro-grid storage system was painted by using The basic painting mechanismof VC. The animation effect of Distributed micro-grid storage system running wascompleted by using Double Buffering. The beautify of interface was designed by usingFlash in MFC program. According to the working fundamental of Distributed micro-gridstorage system, a basic algorithm was coded and run successfully, which told the programhow to run at a certain environment conditions. The demonstration system clearly showsthe operational aspect of the Distributed Micro-grid Storage System to the user underdifferent environmental conditions, having man-machine interaction ability. It makesnon-professional understand the Distributed Micro-grid Storage System deeply. And as akind of promotional medium, it greatly improved the popularization of DistributedMicro-grid Storage System to bring a steady business opportunity for companies.
