“…Nevertheless, in selecting the required remedial actions, this method did not consider the capability of transmission systems to transfer power to load areas. Neglecting the capability of generation and distribution systems, the integral square voltage magnitude indicator, based on bus voltages measured by phasor measurement unit (PMUs), has been suggested to perform response-based remedial actions [20]. An adaptive load shedding method has also been presented [21], in which the load shedding amount is determined according to the system frequency and the voltage falling rate to preserve the frequency and voltage stability of the power system.…”

The main objective of this article is to propose a special protection system (SPS) to execute efficient remedial actions to prevent mid-term and long-term voltage instabilities. In this method, when the operating point (OP) leaves the normal operation state, the proposed SPS is initiated to execute the required corrective remedial actions to bring the OP back to a normal state and maintain bus voltages above prespecified thresholds. Considering the local nature of Volt/Var control and in order to execute fast remedial actions, in this approach, the required generation rescheduling or load shedding procedures were selected based on the electrical distance concept. This allows for remedial actions with the highest impact on volt/var control. In addition, in generation rescheduling procedures, the proposed method uses the ability of utility-scale photovoltaic resources, which can change their generation quickly. This plays a major role in maintaining stability of power systems. Efficiency of the proposed algorithm was validated through several scenarios performed in IEEE 39-bus, Nordic32, and PST 16 test systems using DIgSILENT PowerFactory software. Results of these dynamic simulations and their comparison with some previously published methods show the effectiveness of this method in timely executing appropriate remedial actions to maintain system stability.
