Title:
MPPT CONTROLLER, SOLAR BATTERY CONTROL DEVICE, SOLAR POWER GENERATION SYSTEM, MPPT CONTROL PROGRAM, AND CONTROL METHOD FOR MPPT CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2011/089959
Kind Code:
A1
Abstract:
In order to perform control at an estimated maximum power point even at an unknown operating point, disclosed is an MPPT controller (20) provided with: a measurement data acquisition unit (31) which acquires a solar radiation amount and/or a temperature from a pyrheliometer (14)/a thermometer (15) and acquires a current value and/or a voltage value from an ammeter (17a)/a voltmeter (17b); a search control unit (34) which controls the operating point of an array (10) by controlling an inverter (18) to search for a maximum power point; an estimate equation calculation unit (32) which estimates an estimate equation (A) that holds between the solar radiation amount and the maximum operating current value and/or an estimate equation (B) that holds between the temperature and the maximum operating voltage value; and an MPP estimation unit (35) which estimates the maximum power point at a certain solar radiation amount or a certain temperature using the estimate equation (A) or (B).
