Medium and Short-term Complementary Operation of Hydro-photovoltaic Considering Dynamic Control of Reservoir Water Level in Non-flood Season
To solve the multi-time scale coupling scheduling problem of the large-scale hydro-photovoltaic comple-mentary system in non-flood season,the basic principle of short-term hydro-photovoltaic complementary under the dy-namic control scheduling mode of reservoir water level was expounded.The mathematical models of medium-term and short-term multi-objective optimal scheduling of hydro-photovoltaic complementary considering the dynamic control of reservoir water level in non-flood season were established respectivel.The effectiveness of the models was verified by tak-ing Banduo hydro-photovoltaic complementary system in the upper reaches of the Yellow River in Qinghai Province as an example.The results show that compared with the traditional dispatching mode,the daily initial reservoir water level in non-flood season increases by 0.94-1.17 m on average,and the average daily hydropower generation head increases by 0.06%-0.80%under the reservoir water level dynamic control dispatching mode.In non-flood season,the power genera-tion of hydro-photovoltaic complementary system increases by 0.221%,and the amount of photovoltaic power curtail-ments decreases by 0.025%.Therefore,the dynamic control of reservoir water level in non-flood season can improve the medium-and short-term hydro-photovoltaic complementary performance.
