Various Approaches to Addressing Unit Commitment Issues in Electric Power Plants

الملخص

In this work, the Unit Commitment (UC) problem has been investigated.   In order to ensure that the demand for energy is constantly met at the lowest feasible cost, the challenge is in determining which subset of generating units within a power system is particularly effective.    Additionally, heuristics, dynamic programming, and Lagrangian relaxation are some of the approaches that are being researched.  The uniform convergence (UC) problem is characterized by a number of intrinsic complexities, and each of these techniques is designed to accommodate those complexities.  There are a great number of operational restrictions that are responsible for these levels of complexity.  These kinds of limitations include things like the requirements for the spinning reserve, the restraints on the thermal unit, the availability of fuel, and the emission regulations.  The purpose of this research is to provide light on the effectiveness of a number of contemporary optimization approaches, including enumeration methods, integer programming, and evolutionary algorithms, among others. This research examined how a regional power system operated normally and under emergency situations by studying distribution of power loads alongside generator capacity as well as backup reserves and inter-regional power transfer. The analysis examined both major power plant outages which disrupt the system balance especially when units 7 and 8 fail and what happens when power demand exceeds capacity. The analysis demonstrated that the system has acceptable performance during regular operations but significantly depends on Southern region resources after unit failures cause reduced spinning reserves with substantial interchanges occurring. Tests of increased power demand confirmed that Eastern and Western regions faced essential power deficits reaching 650 MW. System reliability depends on proper distribution of generating sources combined with strategic reserve margin reinforcement together with improved power flow flexibility between regions.
