Economic case study of on-grid wind-pumped storage hybrid system in a hydroelectric plant of Tamil Nadu

Abstract

Evolution in the field of hydroelectric-power station is depends on precipitation pattern but diminish rainfall leads to shortfall of water in hydroelectric plant's reservoirs due to climate change. To get vindicated solution from this problem, normal hydroelectric plants may be re-planed by pumped storage units incorporating with wind energy. Wind energy is mostly carbon-free and can give standby mode to the hydropower station for continuous electricity-generation. The present study has been carried out in a small barrage of Tamil Nadu, India, to get economic power outage. A real-time data-based hybrid energy system is proposed in an existing barrage to get more facilities from renewable resources. So, we are expected to get economic growth over the lifetime with challenges of unpredictable inputs, seasonal variation, and fluctuating loads. Study concluded that wind energy with a pumped hydro storage system is a serviceable choice for restoring the execution of small hydroelectric barrage.
