Unit Commitment-Security Constraints Using the Priority List-Genetic Algorithm Method in the IEEE 6 Bus and IEEE 14 BUS Case Studies

<p><strong>Unit commitment (UC) is the scheduling of on-off operation of a power plant unit to meet the demand for electrical power over a certain period of time in order to obtain an economical total cost of generation The PL method is used for scheduling and the AG is optimized using DOE for ED problems. The results obtained from the research that there are still improvements in the calculation of ED problems using load flow constraints and can be corrected. The results of the comparison of the total percentage cost of IEEE 6 buses used in ED problems without considering the load flow constraints with those considering this problem amounted to 26.30%. The result of the comparison of the total percentage cost of IEEE 14 buses used in ED problems without considering load flow constraints with those considering this problem is 11.55%. The load flow calculation using Newton-Rapshon uses a smaller number of iterations and a shorter time than Gauss-Seidel.</strong></p><p><strong><br /></strong></p>

Load flow analysis is a study to plan and determine the amount of power in an electric power system. During its development, industry requires a large amount of electric power and uses electrical equipment as a means of production. The benefits of an electric load flow analysis are to find out the amount of power in the electric power system whether it still meets predetermined limits, and to find out the amount of voltage at each point, and to obtain initial conditions for the new system planning. Load flow analysis begins calculating the active power and reactive power at each node (bus) installed, loading on the channel or conductor, the load flow calculation will be assisted using the Julia program. From the results of calculations using the Julia program, the voltage at each point with the smallest stress is obtained, namely the 10th point of 209.89 - j10.34V for phase A, -107.39 - j186.87V for phase B, -108.12 + j178,51V for phase CKey Words: Drop Voltage, Julia, Load Flow

Improvement of Long Distance Transmission by Using TCSC Fact Device

The prudent point of view of Flexible AC Transmission System (FACTS) establishment and execution has been an essential issue since origin and expanding each day because of vital, specialized and showcase requirements. The advancement of these issues assumes a significant job in the achievement of any utility and at last minimal effort accessibility of intensity at the client end. This paper exhibits the ideal area of Thyristor Controlled Series Capacitor (TCSC) in control framework to limit the transmission misfortune utilizing Particle Swarm Optimization procedure. The reenactments are performed on the IEEE-14 transport framework, IEEE 30 transport framework and Indian 75 transport framework with Newton Raphson load flow calculation including TCSC
