Zero energy grid injection strategies using comercial inverters in solar energy power generation systems

An electronic equipment reliably that allow to control the generated electric power to be below of the electric power consumption and is able to compensate the electric energy injection into the company distribution grid, complying with the legislation and that is likely to be accepted as a valid system for electricity distribution companies is proposed. This make changes in the output power of the inverters and introducing variable loads to avoid energy injection both in time intervals which inverter power output changes as in the case of power generation over consumption. Thus the electric energy power generation system is used effectively, even when restrictions for energy injection improper exists. © 2013 IEEE.
