Research on the economic feasibility of large-scale hydro-solar power complementary including long-distance transmission
At present, the Solar PV is expected to the most price-competitive renewable energy, with its cost decreasing rapidly.Hydropower is a kind of high-quality and reliable regulating power, and can be bundled with solar PV to improve the economic feasibility of long-distance transmitted power.In this paper, a quantification model is established, taking into account the regulating capacity of the reservoir, characteristics of solar generation, and cost of hydro and solar PV combined with long-distance transmission, based on the installed capacity ratio of Hydro-solar power joint development is studied.The results indicate that for hydropower stations with high regulating capacity and generation factor about 0.5, a hydro-solar installed capacity ratio of 1∶1 will deliver the optimal overall economic performance, and for hydropower stations with daily regulating capacity reservoir and capacity factor about 0.65, the optimal hydro-solar installed capacity ratio is about 1∶0.3.In addition, the conclusions are verified using two cases in Africa by the operation simulation of the hydro-solar complemented system including UHVDC transmission.
