Embodiment Construction

[0090] The present invention proposes a novel water-light complementary multi-objective optimization operation method, the flowchart of which is as follows: figure 1 shown, including the following steps:

[0091] Step 1 Calculate PV power output

[0092] For rotatable photovoltaic arrays using Maximum Power Point Tracking (MPPT) technology, the photovoltaic output is obtained according to the model in the HOMER software developed by the National Renewable Energy Laboratory by comparing the standard test conditions and general conditions:

[0093]

[0094] Among them, P V is the actual PV output, Y V is the rated photovoltaic output; R T is the actual light intensity, R STC is the light intensity under standard test conditions, equivalent to 1000W / m 2 ; η is the temperature coefficient of the power output of the photovoltaic module; T C is the actual temperature of the PV module, T STC is the temperature under standard test conditions, equivalent to 25°C; γ is the sha...

Abstract

The present invention relates to a novel water-light complementary multi-objective optimization operation method. The present invention is implemented in four steps. Step 1 calculates photovoltaic output, step 2 calculates hydropower output, and step 3 establishes a hybrid power generation system that minimizes water-light complementarity. Output power fluctuations, while considering the multi-objective optimization model for maximizing the gains of the hybrid system, Step 4 proposes a non-dominated sorting genetic algorithm based on simulated annealing. The present invention has two major innovations: one is to fully consider the influence of the reservoir on the optimal operation of the hybrid system in terms of flood control, water supply, evaporation, and rainfall when establishing the model of the water-light complementary hybrid power generation system; the other is to establish a dual-objective The optimized simulated annealing mechanism improves the classic NSGA-II algorithm, which is prone to fall into the slow chain state when solving high-dimensional, nonlinear multi-objective optimization problems, and greatly reduces the calculation time cost.

Description

technical field [0001] The invention relates to a novel water-light complementary multi-objective optimal operation method, which belongs to the research field of electric power system optimal operation. Background technique [0002] Hydropower has typical seasonal characteristics of wet and dry periods, and is also affected by short-term random factors such as precipitation, weather, etc. Due to the characteristics of hydroelectric power generation, hydropower plants are usually located in remote areas, about hundreds or thousands of kilometers away from the load center. On the other hand, hydropower plants are also located in areas that are very rich in renewable resources and suitable for large-scale development, such as wind and solar energy. The new energy stations are usually connected to the grid through the loop of the hydropower station, and the hydropower output can be used to adjust its fluctuation and intermittency, thereby providing high-quality power to the gr...
