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.
