Abstract

The rapid expansion of inverter-based renewable generation is reshaping power-system dynamics, particularly in weak and operationally constrained grids. In Pakistan, this transition is driven by concentrated utility-scale wind development in the Gharo–Jhimpir corridor, continued growth of utility-scale solar, and rapid behind-the-meter photovoltaic deployment under net metering. By June 2024, Pakistan’s utility-scale installed capacity reached 45,888 MW, while net-metered solar capacity had increased to 2,498 MW across 157,844 consumers, indicating that transmission- and distribution-level renewable-integration challenges are emerging concurrently. However, existing Pakistan-focused literature has largely emphasized resource potential, policy, and techno-economics, with limited integrated assessment of stability implications. This review addresses this gap by examining the effects of increasing renewable penetration on frequency stability, voltage stability, system strength, oscillatory behaviour, protection performance, and distributionnetwork operability. Six recurrent risk clusters are identified: declining synchronous inertia, elevated rate of change of frequency, weak-grid voltage instability, converter-driven oscillations, reverse power flow in solar-rich feeders, and congestion in renewable-resource corridors. The review further evaluates international mitigation pathways, including grid-forming inverters, battery energy storage, fast frequency response, dynamic reactivepower support, wide-area monitoring, adaptive protection, and stability-oriented grid-code reform. Based on this synthesis, a Pakistan-specific stability framework is proposed, linking inverter performance requirements, staged RMS–EMT studies, strategically located storage, targeted synchronous support, forecasting integration, corridor reinforcement, distribution-level visibility, and updated operational standards. The study concludes that Pakistan’s stability vulnerabilities arise from the interaction between inverter-dominated generation and uneven system strength, limited dynamic observability, transmission constraints, and evolving operational and regulatory arrangements.
