GENERATED ELECTRIC POWER SUITABLE USE SYSTEM BY NATURAL ENERGY

摘要

PROBLEM TO BE SOLVED: To provide a generated electric power suitable use system by natural energy that can use electric power generated with natural energy without wasting by converting generated electric power from power generation facilities using the natural energy into AC electric power and using the AC electric power in combination with transmitted electric power of a commercial power source, does not make a reverse power flow of the generated electric power to the commercial power source side in a case of contingency, and further never wastes the generated electric power even when the generated electric power is less than what is called a prescribed amount.SOLUTION: There is provided an electric power generation system configured to utilize electric power from power generation facilities using natural energy by putting together transmitted electric power sent out by a DC-AC conversion device and AC transmitted electric power by a commercial power source with respect to power generation facilities requiring AC conversion. The DC generated electric power from a plurality of facilities is integrated in advance up to a power generation amount which is large enough for conversion from DC to AC by the DC-AC conversion device.
