As energy, the environment and other issues become increasingly prominent , there is a growing emphasis on distributed generation technologies . However , uncontrollable power , distributed power access to the grid many adverse effects , which restricts the development of distributed generation technology . In order to address the negative impact of distributed power access , micro network as a new type of distributed energy management systems have been proposed . Currently, the micro- network operation and management control and relay protection program is a cutting-edge field of study . In order to study the feasibility and practicality of the micro - network protection and control theory , set up a micro- network simulation system is of great significance . In this paper, a micro- network simulation system design and piconet relay protection program and energy management strategy as a basis for the design . The main contents are: First, the micro - network simulation system design . Micro- network simulation system includes : the synchronization power generation system , double-fed wind power generation system , the direct-drive wind power generation system , photovoltaic power generation system , energy storage system , adjustable load monitoring systems and analog transmission lines subsystems . Secondly , according to the characteristics of the various subsystems of the micro - network simulation system , combined with the the Distributed power of access relay protection , designed a micro- the network relay protection scheme , the relay program over with the direction of atresia current I segment protection, over voltage protection and wide-area backup protection . Finally, the combination of load forecasting , forecast Distributed Power -line monitoring of the storage battery capacity , using the method of least squares , nonlinear programming methods such as design the the piconet simulation system energy management program .
