Optimal parameters of inverter-based microgrid to improve transient response

Abstract

The inertia issues in a microgrid can be improved by modifying the inverter control strategies to represent a virtual inertia simulation. This method employs the droop control strategy commonly used to share the power of a load among different power sources in the microgrid. This paper utilizes a modified droop control that represents this virtual inertia and applies an optimization algorithm to determine the optimal parameters and improve transient response. The results show better control when different variations are presented in the loads, leading the microgrid to have a better control of the operation. The optimization method applied in this research allows improvement to the transient response, thus avoiding unnecessary blackouts in the microgrid. : received his Bs. degree in Electrical Engineering and his Master in Electrical Engineering from the Universidad Nacional de Colombia, Sede Medellín.

Demand side management in a microgrid to reduce the peak consumption cost

“…The efficiency of output power depends on the conditions like temperature, irradiance, and type of load. As these vary the highest power transfer efficiency varies [20]. To optimize the transfer the load characteristic should operate at maximum power efficiency.…”

The assesement of the shunt active filter efficiency under varied power supply source and load parameters

“…It is undeniable that ensuring power quality improvement and electromagnetic compatibility is critical in centralized power supply systems, distributed generation systems, and combined power supply systems [1][2][3][4]. The main negative influences of the poor power quality level on electrical equipment and power supply systems are well-known and have been studied in detail [5][6][7][8][9][10]. In particular, this problem has become more significant considering the intensive development of technologies and the principles of distributed generation from alternative and renewable power sources and combined power systems, where both centralized and distributed sources work in parallel mode.…”
