Frequency Control by Decentralized Controllable Heating Loads with H∞ controller
Abstract: Many isolated small
power systems are powered by diesel generators, which results in greater
operating costs than interconnected large grids. It is therefore desirable to
integrate renewable energy sources such as wind power into these small grids.
However, due to the fluctuating power generation from renewable energy sources,
frequency deviations of power systems become problematic. Distributed
intelligent load control can be used to significantly increase renewable energy
penetration and cut diesel fuel consumption. This paper presents a methodology
for grid frequency control by electric water heaters as controllable loads.
This system consists of diesel generator, wind farm, and loads. By applying a
power consumption controller adopted from H∞control theory, grid frequency
deviation is maintained around rated value. In order to verify the
effectiveness of the proposed system, MATLAB/Simulink is used for simulations.
