The advent of microgrids paved the way for energy decentralization and self-sufficiency among consumers. Reciprocating engine driven synchronous generators (also known as gensets) are one of the most commonly found distributed energy resources (DERs) installed in a microgrid. A key concern in microgrid operation is the frequency regulation, especially when it is islanded from the main grid. In recent...
Natural gas powered inverter-based distributed energy resources (DERs) are becoming increasingly popular. In such DERs, the output frequency is decoupled from the prime-mover speed. This is advantageous in terms of improved efficiency and reduced emissions for the internal combustion engine. However, under large load conditions the prime-mover can stall leading to a voltage collapse. This paper presents...
Reciprocating engine driven generator sets (or “gensets”) are a leading class of distributed energy resources (DERs) from the low kilowatt up to hundreds of kilowatt ratings. Natural-gas-based DERs are more likely to be favored by both industries and utilities in the near future because of their low cost due to the newly found shale deposits at many places in the world. The DERs such as gensets when...
Natural gas based distributed energy resources (DERs) are likely to be favored by electric utilities in the near future because of the newly found shale deposit resources. Reciprocating engine based generator sets are a leading class of energy conversion equipment from the low kW upto 100s of kW ratings. Standalone engine generator sets with isochronous governors are susceptible to stalling when they...
