Detailed Documentation

This case study explores the application of Particle Swarm Optimization (PSO) to solve the Unit Commitment Problem (UCP). The UCP represents a challenging optimization task in power systems that involves determining the optimal combination of power generation units while satisfying operational constraints. The implementation typically includes key functions for initialization, fitness evaluation, velocity updates, and position updates. The algorithm maintains a swarm of particles where each particle's position represents a potential solution (unit commitment schedule), and velocities are updated based on personal best and global best positions. Fitness functions incorporate constraints like minimum up/down times, ramp rates, and load demand requirements. This practical example provides valuable insights into constraint handling techniques and optimization strategies that can be adapted to similar complex problems in power system optimization.
