Voltage compensation in weak distribution networks using multiple shunt connected voltage source inverters

摘要: Voltage regulation of long weak distribution lines is a challenging problem, particularly when it not economic to upgrade the entire feeder system. Power electronic converter systems offer an attractive alternative, with their potential provide both steady state and transient voltage compensation for limited capital investment. However, operation these networks and/or multiple distributed installations needs careful attention avoid unexpected interactions achieve optimum performance. This paper explores use D-STATCOM compensators stable dynamic profile along radial network under widely varying load conditions. Both simulation experimental results are presented.
