Summary
As India targets 500 GW of non-fossil capacity by 2030, the rapid integration of large-scale hybrid renewable energy plants (Photovoltaic(PV), wind, and storage) introduces significant operational complexity [1][2]. The intermittent nature of these multi-asset plants poses challenges for frequency stability, voltage profiling, and grid code compliance at the Point of Common Coupling

Controller (MPPC) designed to orchestrate the dynamic behavior of heterogeneous renewable assets.
Unlike traditional controllers, the proposed MPPC implements a hierarchical logic that coordinates active power dispatch with dynamic ramp-rate limits and manages reactive power through configurable Q(V) droop and power factor control. Crucially, it harmonizes conflicting dynamic responses from PV inverters and wind turbines to satisfy Frequency Response Obligations (FRO) and LV/HV Ride-Through requirements (LVRT/HVRT). The architecture is implemented on redundant Remote Terminal Units (RTU) with embedded cybersecurity protocols to ensure operational resilience. Results from a deployed case study demonstrate that this strategy significantly reduces curtailment, optimizes dispatch scheduling, and ensures strict adherence to grid codes, effectively transforming hybrid plants into dispatchable, grid-forming energy hubs.
