Abstract
Microgrids are often accomplished with power-dense and energy-dense hybrid storage systems for the assured improvement in the stability and the awake time. The conventional droop based steady-state power bifurcation strategies for the energy-dense storage elements can efficiently improve the awake time. However, the improvement in the stability and the robustness demands accurate transient demand allocation. The constant cut-off frequency-based physical power decomposition filter cannot ensure an accurate transient demand allocation, particularly, while the demand is fluctuating and uncertain. Therefore, the study proposes the concept of pseudo-power decomposition filter. The concept of the pseudo-decomposition filter has been executed for the microgrid through the novel selected power component droop. The real-time performance of the proposed concept has been evaluated in the BTS-7960 packaged-Metal Oxide Semiconductor Field Effect Transistor (MOSFET)-based hardware platform, regularised through the ARM Cortex A-72 based digital signal processor. In respect to the conventional linear droop, the improvement through the concept in the power decomposition and the allocation of transient demands is significant.
