Dear Dr. Ray and Ahmed, This is true from what Dr. Ray said before. I have done a similar project before to handle the energy storage management integrated into a distribution network by using the DC OPF, then modifying dcopf module by extending the corresponding matrix for the customized parameters. There are a lot of reference papers to achieve this goal, I only used dcopf, because I built a simpler model and suitable for my requirements.
