Integrating IAC Aggregators into SMG for Enhanced Frequency Control with Multiple VSGs

This study presents a novel research model that integrates an IAC aggregator into the SMG (Smart Microgrid) to enhance frequency stability. The model addresses the challenge of potential oscillations and instability often associated with integrating renewable energy sources. To mitigate these issues, a multi-VSG (Virtual Synchronous Generator) based frequency control strategy is proposed. This strategy focuses on regulating new energy loads, such as Solar Water Heaters (SWE) and Photovoltaic (PV) systems, effectively contributing to grid stability.

As depicted in Figure 2, the implementation of this control strategy allows for the derivation of the state-space frequency response. This analysis provides valuable insights into the system's dynamic behavior and validates the effectiveness of the proposed approach in maintaining stable grid operation.
