The microgrid system with a high share of Renewable Energy Sources (RES), is the need of hour. The RES provides clean, economical and never-ending active power support to the system. However, the inertia deficiency is the negative side of RES based systems, as it adversely affects the dynamic performance of the microgrid and may lead to severe consequences like loss of synchronization and instability. For addressing the issue of inertia deficiency, several techniques were already proposed for emulating the virtual inertia. Among these, the Derivative Control Technique (DCT) is quite popular, because of its simplicity and effectiveness. The previous research work utilizes the Energy Storage System (ESS) for providing virtual inertia support through DCT during load imbalance. However, such a system neglects the possibility of extracting virtual inertia support obtained from RES. This paper proposes a novel technique for tapping the virtual inertia potential of RES (Photo Voltaic system), by cultivating the the derivative control mechanism and further improves the dynamic performance of the system. Further, the efficiency of the proposed system is evaluated through time-domain simulations under different scenarios and compare it with conventional and ESS based systems.

微电网系统需要大量的可再生能源（RES）。RES为系统提供清洁，经济且永无休止的有功功率支持。但是，惯性不足是基于RES的系统的不利方面，因为它会对微电网的动态性能产生不利影响，并可能导致严重的后果，如失去同步性和不稳定性。为了解决惯性不足的问题，已经提出了几种模拟虚拟惯性的技术。其中，导数控制技术（DCT）由于其简单性和有效性而非常受欢迎。先前的研究工作利用能量存储系统（ESS）在负载不平衡时通过DCT提供虚拟惯性支持。然而，这样的系统忽略了提取从RES获得的虚拟惯性支持的可能性。通过培养微分控制机制，进一步提出了一种利用RES（光伏系统）虚拟惯性势的新技术，进一步提高了系统的动态性能。此外，通过在不同情况下进行时域仿真来评估所提出系统的效率，并将其与常规系统和基于ESS的系统进行比较。
