Abstract:

Both the output of hydropower and photovoltaic (PV) are related to weather conditions. Hydropower is able to quickly adjust and has the capacity of energy storage, which can be complementary with the PV operation and compensate the intermittent of solar energy. At present, the papers that study the complementary characteristics of these 2 kinds of power supply in different time dimension are less. This paper proposed the analysis method for the complementary characteristics of hydropower and PV power, established the evaluation index for the synergy between hydropower and PV power based on the thermal generation load factor and PV curtailment ratio, and calculated the evaluation index for the synergy between hydropower and PV power with using the chronological simulation of PV output and the operation simulation of the power system with hydropower. Taking the planning data of power system in Qinghai Province in 2020 as example, the characteristics of the synergy between hydropower and PV power in Qinghai Province in 2020 were studied, and some suggestions were proposed for the synergy operation between hydropower and photovoltaic power in Qinghai Province in the future according to the calculation results.

Key words:  synergy between hydropower and photovoltaic power, operation simulation, peak off-peak regulation, thermal generation load factor, photovoltaic curtailment ratio
