The impact of renewable energy resources and energy storage systems (ESS) on power system operation is examined in this study, with a focus on their ability to provide primary frequency reserve, alleviate capacity needs, manage congestion, support voltage and reactive power, and enhance reliability at reduced costs. Specifically, the integration of wind energy with ternary pumped-storage hydropower (T-PSH) and conventional pumped-storage hydropower (C-PSH) systems is assessed using a 10-bus system and GE Positive Sequence Load Flow (PSLF) software. Various contingency scenarios, including wind farm generation loss and loss of load, are considered to evaluate the performance of the system. The study aims to optimize the dynamic models and grid connection of PSH systems to maximize their effectiveness and fulfill grid load requirements.
