| Abstract | Optimization problems in short-term generation scheduling have been had an attraction from system operators for decades. Due to intermittence of wind velocity, unexpected change in water inflow to reservoirs, load variation, inaccurate weather forecast, complex technical constraints, and dramatic increase of the number of units in the system..., they drive optimization function to be a non-linear, non-convex and high dimension problem. This thesis aims to optimize dispatch of hydro-thermal generations while considering wind power in the system. The objective is finding optimal output power of each unit in the system subject to technical constraints (thermal, hydraulic, wind constraints) in order to minimize the total operating cost of the power system. Pseudo-Gradient Based Particle Swarm Optimization (PGPSO) is used to solve the problem. The program is coded and run in Matlab environment then apply it to the case study in Viet Nam. 24-hour economic outputs of different units in the system are calculated. This optimization method shows its feasibility, usefulness and should be further developed by people who interest in economic load dispatch. |
