Abstract
The Security constraints unit commitment (SCUC) is a powerful scheduling technique used in power markets for daily planning. SCUC is a framework that combines two common algorithms in the electricity industry: Unit Commitment (UC) and Economic Dispatch (ED), while adding a new dimension – Security. Load demand is changing continuously due to variation of load of industrial, residential and commercial sectors. Thus, it is very important to decide which generating unit should be kept on and how much power should be dispatched so that time varying load demand can be meet on Hourly basis and there should be no scope of occurrence of loss of load hour (LOLH). In the proposed research, the recently developed hybrid meta-heuristics search algorithm i.e. GWO-RES has been applied to solve the security constrained Unit Commitment and dispatch problem of Electric power system. The efficiency of the proposed hybrid algorithm has been tested for standard IEEE-14 Bus, 30-Bus and 56-bus system and it has been experimentally found that GWO-RES performs much better than hybrid GWO-PS and GWO-RS algorithm.
Highlights
Security Constrained unit commitment and dispatch effort pair in power generation industry to empower grid management and power generation, along with ensuring proper dispatch of power on hourly basis
It is necessitated that the arranging of producing units is to be done in such a way, that there is sufficient amount of power generation accessible to satisfy the demand of the electrical load along with maintain malfunctions and failures under adverse conditions

Summary
Security Constrained unit commitment and dispatch effort pair in power generation industry to empower grid management and power generation, along with ensuring proper dispatch of power on hourly basis. The demand of electric power is changing continuously and achieves various peak values In this way, it is essential to choose which power generation units have to turn on and in which hour it is required in the power system framework arrange and for what time period the generating unit should keep in shut down condition to main the cost viability of turning on and closing down of particular unit. Unit responsibility handle the power generation plan for electrical system for minimize fuel and operational costs while fulfilling system and constraints, for example, demand of electrical load and system save necessities over a set of time spans. Of power generating unit cost by maintaining LOLH and satisfying some physical and system constrains forced on the system, for example, SRh = Spinning reserve necessity operating constraint, load-power generation balance, spinning reserve, minimum down time horizon and. The main objective of security constrained unit commitment problem is to minimize the total operating cost with satisfying those constrains
