Title:
POWER CONTROL METHOD FOR WIND POWER AND PHOTOVOLTAIC COMBINED POWER GENERATION
Document Type and Number:
WIPO Patent Application WO/2024/041590
Kind Code:
A1
Abstract:
A power control method for wind power and photovoltaic combined power generation comprises: Step 1, acquiring a wind strength parameter and a light intensity parameter of a wind power and photovoltaic combined power generation system, and acquiring the current operation characteristics of the power generation system; Step 2, determining a first power regulation quantity for the power generation system on the basis of the wind strength parameter, and determining a second power regulation quantity for the power generation system according to the light intensity parameter; Step 3, acquiring an optimal power matching condition under the current operation characteristics; and Step 4, according to the optimal power matching condition, determining a power control instruction for the current power output value of the power generation system on the basis of the first power regulation quantity and the second power regulation quantity, and performing power control on power units in the power generation system. The first power regulation quantity obtained by means of the wind strength parameter and the second power regulation quantity obtained by means of the light intensity parameter are combined with the optimal power matching condition, so that the power is effectively regulated, and the high efficiency of wind power and photovoltaic combined operation is ensured.
