Abstract:

Renewable energy is one of the cleanest power sources in the world. Renewable energy such as hydropower plays one of the most important roles in power generation in Nepal. Nepal is a developing country with an enormous potential of hydropower having more than 6,000 rivers and more than 90% of electricity is producing from Run-of-River hydropower. However, the existing power generation is not sufficient to fulfill the demand and every day importing a huge amount of electricity from its neighboring country India. To reduce the power shortage and to serve Nepal’s economy, cascade hydropower (multi-dam) are the most promising available renewable energy sources. In this paper, the economic load dispatch (ELD) and optimal power flow (OPF) analysis model is developed. The designed model was used to identify the optimal scheduling and to predict the electricity extreme conditions such as an emergency, earthquake, disaster etc., which Nepal is facing oftenly. The main objectives of this research are to determine an optimal technique to overcome the power shortage and identify the optimal power flow. It has been analyzed the optimal power flow analysis and behavior of the whole system. Besides this, the proposed model shows how to reduce the imported power and balance the system.<
