Dear respected developer, I am Ahmad, currently doing research on Optimal Power and Gas Flow (OPGF). I tried to merge the electrical power system with the gas system to obtain the optimal power and gas flow. But, I face some problems when I concatenated the equality and inequality matrix (g, h, dg, dh, d2G, d2H). I have already added the optimization variable and built the aforesaid matrix as well as its derivatives. But, when I run the program it shows "Numerically Failed" and "Did not converge in 10 iterations.". Could you help me to explain what other steps that I need to do if I want to modify Matpower?
Thank you in advance. *Simulation conducted in Matpower 5.0 *OPF calculation performed using MIPS Regard *Ahmad Bariq Al Fahri* Department of Electrical Engineering Sepuluh Nopember Institute of Technology LinkedIn <https://www.linkedin.com/in/alfahri/>
