Development of Autonomous Demand Area Power System in Criepi

Abstract A large introduction of distributed power generation is expected. Under such circumstance, power flow congestion, voltage fluctuation and degradation of safety on distribution systems will occur by the operation of the distributed power generations. As a strong measure of the issues, we have proposed a unique, new power supply system called “Autonomous Demand Area Power System”. The system leads free access of the distributed power generation to the grid and makes effective use of the generations using power electronics devices and communication network. The paper described concept, composition and operation measures of the Autonomous Demand Area Power System.
