Modeling and Development of Run-of-River Cascade Hydropower Plants in Nepal

Raju Rai and Ken Nagasaka
Abstract—Nepal is a developing country rich in water resources, with an enormous potential of hydropower having more than 6000 rivers. Hydropower plays an increasingly important role in electricity generation in Nepal. To serve Nepal’s economy and reduce the power shortage, cascade hydropower plants are the most promising available renewable energy sources in Nepal. In this paper, we propose a model for a cascade of hydro power plants using multiple dams systems in Trishuli river of Nepal to increase the potential of hydropower and to solve the needs of demand in the country. The output power of proposed cascade hydropower plants are connected to a 66 kV grid. As we know, Nepal is a small country which needs more power and demand is obviously high. In Nepal, Trishuli river is one of the famous rivers having high economic importance and potential water resources. If we construct more cascade hydropower plants in this river, it will enable access to electrification in rural areas as well as reduce the power shortage in local community. Also, it helps to reduce the CO2 emission. This research provides a way to assess the operation of cascade hydropower plants as well as design power plants and verify the potential of electric energy supplied by multi dams rather than a single dam. Grid connected cascade hydropower is implemented for a Kathmandu valley, Nepal. It has been analyzed that the power generated helps reduce the demand for electric power. The developed model is simulated using the Power Systems Computer Aided Design (PSCAD) software. Finally, the simulation models of existing and proposed hydropower plants and its interconnection system are analyzed.

Index Terms—Renewable energy, cascade hydropower, run-of-river, power generation, PSCAD, Nepal.
