Liaoning High-tech Energy Group Co., Ltd and Tsinghua University have achieved the cooperation intent for excogitating the application technology of distributed power station and supply work.     According with the national energy sources policy and environmental prequest, distributed power station and mini supply network and power network can compensate each other and excogitate new type energy sources as well as renewable energy sources, such as : solar energy ,wind energy, geothermal energy, biomass energy and ocean energy etc., and also can implement the integrate utilization and energy conservation and environmental protection of energy resources simultaneously. Liaoning High-tech Energy Group Co., Ltd takes the head in applying the technology of mini supply network alone in our country,and entrusts tsinghua university excogitate the basic theory of the subject. There are 6 types: Type one, the relevant problems of mini supply network including the safty and steady security and optimize operation as well as automtic control of mini supply network. Type two, the relevant problems of of heat engine, which are mainly the mini supply networkoptimize operation and automatic control problems mostly. Type three,the alternative problems for mini supply network and outside supply network, which intends to settle the start-up power optimize collocation and the research of mini supply network start-up modes.Type four, thermoelectricity unite collation and the integrate utilization of energy sources, and its core target is to improve the thermal efficiency. Type five, the utilization of renewable nergy sources. Type six,energy storage and research of its utilization in mini supply network application. Among them, the main target of first four subjects is to settle the problems in the practical engineering practice, the last two subjects belong to exploratory research.
