The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to the Department of Defense, Executive Services and Communications Directorate (0704-0188). Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. At present, there is a need to design a distributed and autonomous subset of a larger grid or a microgrid to increase the security and reliability of electricity supply. The objective of this work was to model and simulate a specialized microgrid called an Intelligent Distributed Autonomous Power Systems (IDAPS), which play a crucial role in building a scalable power grid that facilitates the use of renewable energy technologies. Microgrid device models, including distributed energy sources and loads, as well as their control algorithms, were developed. Several case studies were simulated to evaluate the operation of the IDAPS microgrid during parallel and islanded operation modes. Simulation results indicated that the proposed IDAPS control model was able to: (i) perform demand management during normal operating condition; (ii) island the microgrid from the main grid once an upstream fault is detected; (iii) secure critical loads and shed non-critical loads according to the given priority list during emergencies; and (iv) resynchronize the microgrid to the main grid after an upstream fault is cleared.

Frequency Control of an Islanded Microgrid based on Intelligent Control of Demand Response using Fuzzy Logic and Particle Swarm Optimization (PSO) Algorithm
Due to the increasing penetration of renewable energies in the power system, the frequency control problem has attracted more attention, while the traditional control methods are not capable of regulating the frequency and securing the stability of the system. In smart grids, demand response as the frequency control tool reduces the dependence on spinning reserve and high cost controllers. In a...
