Popis: In islanded Microgrids the load step capability of gas engine driven Combined Heat and Power plants may be exceeded in case of a severe load step. As a result, the engine could be damaged or the generator protection system could be triggered causing a loss of generation. Such a limited robustness of system operation might render backup power supply islands useless under real world conditions. This paper presents an approach for integrating a grid supporting inverter of a battery system into a Microgrid. An existing transient droop approach is modified and then applied to achieve an adjustable transient load relief for a Combined Heat and Power plant. In case of a severe load step it can be demonstrated via simulations that the inverter is able to reduce maximum overshoot and settling time and thus to enhance the Microgrid’s robustness.
