The present invention relates to a grid system for supplying power to a black box for a vehicle by means of photovoltaic power generation, the grid system comprising: a solar cell unit for generating power by using photovoltaic power generation; a main system for supplying a black box with the power generated from the solar cell unit; and an internal battery for storing the power which is from the main system and generated by a solar cell unit. The effectiveness is provided in which, if photovoltaic power generation is not performed due to a change in the amount of sunlight or the vehicle's parking state, discharging of a battery inside a vehicle is prevented by enabling the supply of power first from an internal battery that stores the power from photovoltaic power generation.

A power generation amount prediction apparatus includes a first detector, acquisition unit, database, and controller. The first detector detects a measured value of the power generation amount of a photovoltaic power generation device. The acquisition unit acquires a predicted value of the power generation amount by the photovoltaic power generation device at specific times. The database stores the measured value and the predicted value for each of the specific times for a plurality of days. The controller calculates a corrected predicted value for each of the specific times based on a maximum measured value, a maximum predicted value, and a predicted value newly received by the acquisition unit. The maximum measured value and the maximum predicted value are respectively the maximum value, for each of the specific times, of the measured value and of the predicted value for a predetermined number of days.

A method of controlling a photovoltaic system includes: receiving a forecast of energy generation by the photovoltaic system for a predetermined time period; determining a revenue generation objective function characterizing revenue generated by feeding electrical energy from the photovoltaic system into an energy transmission system; determining constraints on the feed-in of electrical energy into the energy transmission system, at least some of the constraints being a function of the forecast; optimizing the revenue generation objective function as constrained to determine energy feed-in and storage actions; and executing the determined energy feed-in and storage actions. The method, for example, utilizes a simplified revenue generation module including a linear revenue generation objective function and a plurality of linear constraints, which can enable optimization using a mixed integer linear programming approach. The method steps can be performed iteratively, at each of a plurality of predetermined time intervals during the predetermined time period.

An inverter (100) and a photovoltaic power generation system. By arranging an energy storage interface (103), redundant direct-current electric energy of electric energy output by a solar panel (200) can be output through the energy storage interface (103) when photovoltaic power generation is limited, and stored direct-current electric energy can be received through the energy storage interface (103) when the photovoltaic power generation is at a low power. Therefore, the electric energy output by the solar panel (200) is not wasted, and the photovoltaic power generation system can generate power at a maximum power without lowering the profits of photovoltaic power generation.
