Đánh giá hiệu quả thay thế của nhà máy thủy điện mở rộng

Abstract

In order to integrate renewable energy sources with an increasing proportion, the development of expanded hydropower stations is currently an effective solution to help the power system operate stably and safely. Up to now, there is no mechanism and policy on electricity price for expanded hydropower stations. The article presents a methodology to assess the replacement efficiency of expanding hydropower stations, which is the basis for building the mechanism and policy on electricity price for the expanded hydropower stations. Results from applying calculations for the two periods 2020-3029 and 2030-2045 have selected the most reasonable replacement power source option when calculating the investment in expansion hydropower station projects to bring efficiency in actual operation
