Some aspects of the computational complexity in the design of islanded microgrids, design and analysis of blackstart sequences for a notional microgrid

The US grid represents more than ;A microgrid is capable of disconnecting from the main grid, on sensing a disturbance on the main grid, to maintain reliable supply of electricity to the constituent end-user loads. In this work, the computational complexity of the design of islanded microgrids by the optimal addition of network feeders in a legacy radial electric distribution system is identified, and a technique to accelerate the process of finding Pareto optimal solutions to the problem is provided. The next part of this thesis models a notional microgrid with blackstart capabilities. Microgrids that cannot continue uninterrupted supply to all local loads on disconnection from main grid are required to follow a sequence for startup which is known as the blackstart sequence. In this work, the various generation resources in the notional microgrid are studied and a blackstart sequence is engineered.
