Balancing islanded residential microgrids using demand side management

Now that the internet of things is emerging, control of domestic assets within the smart micro grids is also gaining interest. Furthermore, these micro grids may operate in islanded mode for short periods. Various demand side management approaches are presented in literature to control these assets. However, keeping consumption and production in balance is important in islanded micro grids. This paper proposes a fast control method to control domestic assets in an islanded micro grid by means of 2-way communication and local measurement data. By using the potential of domestic assets, capacity of backup storage and power ratings of backup generators can be decreased or the operation time of the islanded micro grid can be increased. Simulations show that the proposed method is indeed capable of reducing the storage capacity by up to 90%. Benchmarks also show that over 4500 domestic assets can be addressed in a second by one control node.
