Paralleled operation of voltage-source inverters (VSIs) is currently achieved by using voltage/frequency droop control techniques which requires the knowledge of the system parameters. Otherwise, centralized control techniques with robust communication among VSIs controllers are also used. This paper presents a new control strategy which allows the load sharing between the power sources of an ac microgrid...
Recently the microCHP (small scale Combined Heat and Power generation unit — mCHP) systems are more common, however these systems don't have any control or protection which would meet the Smart Grid philosophy. Regular mCHP is unable to effectively manage a power outage. In this paper we investigate the base requirements of control and protection system for one (or more) mCHP if we would like to operate...
