The liberalization of electricity market, technological advances and increased environment concerns, together with raised interest in low capital and opportunities to provide a fast return on investment, have all led to growing interest in small-scale distributed generators. In a stand along operation, a distributed generators Governor and AVR (Automatic Voltage Regulator) are used to ensure the output frequency and voltage are maintained to the set point. When operating in parallel with the grid supply, the distributed generators output frequency and voltage are determined by the networks frequency and voltage controllers. The paper reviews the methods used for to control the wide variety of distributed generators and their influence on the operation of both the generator and the network. It also explores the techniques used for distributed generators using synchronous machines where the governor is used to control the power output to the network and its AVR is used to provide either a pre-set VAR output or to control the output power factor. Naturally, these have a significant ability to influence both the generator and the network to which it is connected. They also offer the opportunity of providing auxiliary services to the network operator in maintaining supply during network disruptions and ensuring that the supply is maintained within regualtory operating constraints. This paper describes the opportunities for a new distribution control scheme that is able to adapt to local conditions both to maintain supply within statutory limits while maximizing power delivery to the network. The scheme is optimized to use the minimum of communications and to maximize continuity of supply when the network is disturbed.</style></abstract><issue><style face="normal" font="default" size="100%"></style></issue><work-type><style face="normal" font="default" size="100%"></style></work-type><accession-num><style face="normal" font="default" size="100%"></style></accession-num><call-num><style face="normal" font="default" size="100%"></style></call-num><notes><style face="normal" font="default" size="100%"></style></notes><custom1><style face="normal" font="default" size="100%"></style></custom1><custom2><style face="normal" font="default" size="100%"></style></custom2><custom3><style face="normal" font="default" size="100%"></style></custom3><custom4><style face="normal" font="default" size="100%"></style></custom4><custom5><style face="normal" font="default" size="100%"></style></custom5><custom6><style face="normal" font="default" size="100%"></style></custom6><custom7><style face="normal" font="default" size="100%"></style></custom7><research-notes><style face="normal" font="default" size="100%"></style></research-notes><num-vols><style face="normal" font="default" size="100%"></style></num-vols><orig-pub><style face="normal" font="default" size="100%"></style></orig-pub><reprint-edition><style face="normal" font="default" size="100%"></style></reprint-edition><section><style face="normal" font="default" size="100%"></style></section><auth-address><style face="normal" font="default" size="100%"></style></auth-address><remote-database-name><style face="normal" font="default" size="100%"></style></remote-database-name><remote-database-provider><style face="normal" font="default" size="100%"></style></remote-database-provider><label><style face="normal" font="default" size="100%"></style></label><access-date><style face="normal" font="default" size="100%"></style></access-date></record></records></xml>
