ABSTRACT
Micro Power Grid has e a power system in some developed countries to solve the problems of an important means of support,distributed generation power industry of the 21st century,the development of direction. With the power grid in the number of distributed generation systems have increased,in particular,is based on renewable energy and power work devices in the distributed power generation system in the application of the increasingly widespread,with the world scientific and technological advances in today's power grid load attendant is constantly increasing problem,the solution of current power system in the many researchers question has e paramount issue.
Text aims to introduce micro-power grid in the application of the research and development trend,first of all,today's power grids on a whole situation and expounded on this background and significance of the ,from the concept of micro-power grid,structure,the whole unit, storage elements,models,the advantages of micro-power grid and grid-connected with the local power grid and other aspects of the brief introduction to micro-power grid. Third,introduced a micro-power grids in the United States,Japan,Europe and other developed countries on the development status and bined with Chinese energy strategy and the development of the micro-power grids in Chinese development potential and prospects to their ,micro-power grid in the study by the three hot issues of micro-grid power grid protection and control of micro-a
