An Object-Oriented Programming Approach to Security-Constrained Unit Commitment Problem

This paper presents the solution of Security-Constrained Unit Commitment Problem (SCUCP) using the simulated annealing method with memory component (MSA). The Unit Commitment solutions without operational and power flow constraints are not practical due to the secure operation of the power system network. The algorithm was developed in an Object-Oriented fashion, in the Delphi programming environment. This approach improves the ability to deal with several different objective functions and constraints, providing flexibility, maintainability, and usability to the development and evolution efforts without degradation of the computational time. The effectiveness of the proposed technique is demonstrated on IEEE 57-bus system (7-generators, 80-lines and 42-loads).
