@daas.shukla @karthikram0 Size of Jacobian Matrix is : J=[n]×[n] , for general n bus power system. J=[2n-2]×[2n-2] , when PV/Voltage controlled buses are abscent (one bus taken as slack bus by default for load flow problem to converge). J=[2n-2-p]×[2n-2-p] , where p= No. of PV/Voltage controlled buses. Given, n=15 & p=3. So, J=[2×15-2-3]×[2×15-2-3] =[25]×[25]
