Distributed generation nanogrid load control system

As the world´s population becomes more reliant on power, the stability and reliability of power systems also needs to increase. One avenue of research is distributed generation (DG) which decreases the need for long distance distribution. As the generation is close to its point of use, the system becomes better equipped to endure extreme weather events and natural disasters. However, DG is typically renewable energy, which presents its own difficulties, such as, intermittency. This paper proposes a nanogrid control system which will increase the efficient use of DG renewable energy sources. This nanogrid controller implements local source/load control, demand side management, a hierarchical load algorithm and interfaces with a national grid. Simulations show that by implementing the demand side management, the amount of power purchased from the grid can be decreased by up to 23%.
