Optimal Operation Planning for Orchestrating Multiple Pulsed Loads With Transient Stability Constraints in Isolated Power Systems

Power systems used on shipboards, airplanes, and similar applications are usually classified as isolated power systems (IPSs), where pulsed loads are very important under both normal and extreme conditions. Because of the high energy density of pulsed loads, stable operation of an IPS with multiple types of pulsed loads faces great challenges. This paper proposes an optimal operation planning of IPS with multiple pulsed loads while considering stability constraints. To mitigate the negative effect of pulsed loads, energy storage devices are used to buffer the required energy. The stability constraints are derived from a proposed analytical criterion whose feasibility is guaranteed by fully studied principles. A critical point-based particle swarm optimization algorithm is proposed to solve the optimal planning problem. The case studies on a typical IPS with multiple pulsed loads verify the correctness and effectiveness of the proposed method.
