INTEGRATION OF MICRO HYDRO WITH NEW RENEWABLE ENERGY TECHNOLOGY FOR RURAL ELECTRIFICATION

摘要

Due to low power density, unpredictable site conditions and up-front cost, new renewable energytechnologies (RET) are not so popular in Nepal. Decades of experience in micro-hydro technology alsosuggests that the rural electrification technologies would widely be disseminated only when they providegrid quality and cheap energy to the rural populace. The rapid investment in rural electrification is alsodecelerated due to the lack of proper site specific data and appropriate tools for their immediate analysis. Inthis regards, we are developing a model that may expedite the decision making process for the planning ofrenewable power mix systems from a set of easy available data input. This paper deals with the basicconcept of this model and some preliminary test results obtained by investigating the performance of ahypothetical mini isolated grid in a mountainous region of Nepal. The present objective is to investigate theoptimum integration of micro-hydro with new RET aiming to create an effective, flexible and reliable powersystem at the same time. The test results suggest that the model is capable for quick assessment of such anintegrated system.
