Herewith i attached the matlab codes for Contingency analysis, Economic dispatch,Pv curve,Swing Curve, Ybus Inspection method and Zbus. I hope these are very useful.

Designs a frequency-domain and time-domain FIR equalizer for a single-input single-output (SISO) channel. Frequency-domain equalization uses a Chebychev criteria and is specified in terms of frequency response functions. It is a convex problem (which can be formulated as an SOCP): ( where H is the frequency response function and our variable is the filter impulse response h. Function G is the unequalized frequency response and G_des is the desired freq response. Time-domain equalization immediately designs the impulse response function by specifying the problem in time (it s an LP): minimize max_{t neq D} |g_tilde(t)| s.t. g_tilde(D) = 1 )
