As the amount of non-scheduled small scale distributed generation (DG) units are increasing, lack of fault ride through (FRT) capability of these generators may have an adverse affect on the overall power system. This study focuses on the basics of transient overvoltage issue arising under faulty condition with integration of power-electronic (PE) interface based DG units in a system. Reasons behind...
Wide-scale penetration of small distributed generation (DG) units to weak distribution systems is one of the major concerns for power system engineers. As grid standards limit reactive power generation capability of small DG units, lack of sufficient reactive power support, brings the problem of slow voltage recovery under post-fault conditions. In this paper, a STATic COMpensator (STATCOM), which...
The penetration level of renewable based distributed generation (DG) has increased rapidly in recent years. Grid standards demand small DG units to operate with constant power factor control mode and large DG units with voltage control mode. As a result, small DG units are exposed to the problem of slow voltage recovery due to contingencies like fault. This paper proposes a new sensitivity index based...
