A METHOD OF EXTENSION OF THE REGULATION RANGE OF ELECTRIC POWER SUPPLIED TO THE ELECTRICITY GRID AND AN ENERGY SYSTEM WITH AN EXTENDED REGULATION RANGE

摘要

The present invention deals with a method and energy system of extension of the electric power regulation range in which electricity produced by an electricity or electricity and heat production source can be supplied in the place of connection to the electricity grid, wherein the regulation range of the source is limited by the maximum installed electric output at the top and the minimum electric output of the source at which it is still possible to operate the source in a stable way at the bottom. According to the invention, before the place of connection to the electricity grid, an electric appliance is installed to the source that will reduce the electric output in the place of connection to the electricity grid below the minimum electric output of the source through its own consumption in the case of demand, extending thus the regulation range of the electric output that can be supplied to the electricity grid in the place of connection as compared to the regulation range of the source alone.
