y bus of power systems for students
no vote
The formation of a bus impedance matrix requires either matrix inversion or the use of involved algorithms.The Z bus is however used for short circuit studies. Since in a power network each bus is connected only to a few other buses (two or three), the Y bus of a large network is very sparse ,i.e, it has a large number of zeroes. The Y bus is often used in solving load flow problems. It has gained widespread applicat

in power engineering , the power-flow study , or load-flow study , is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notation such as a husseinaliraqi 2018-06-21

optimal power flow and economic load dispatch
no vote
Economic dispatch is the short-term determination of the optimal output of a number of electricity generation facilities, to meet the system load, at the lowest possible cost, subject to transmission and operational constraints. The Economic Dispatch Problem is solved by specialized computer software which should honer the operational and system constraints of the available resources and corresponding transmission capabilities.

power flow using Gauss-sidle method to solve power
no vote
this is useful for power flow analysis . This program can be used to verify whether the user's program gives the correct loadflow solution (up to 4 significant figures using Gauss-Siedel method) or not. The program gives intermediate solution. The user should provide the data and the solution in the specified format given below.
The data and the solution obtained by the user should be in a file. All values are in per unit. The data and the solution should be in the form of a table
