In this file　Dynamic simulation of the IEEE 14 bus test case network, with
physical synchronous machine models and photovoltaic inverters (renewable sources).is done in eigenvalue m file. A delta delta transformer modeling is done in the deltadelta simulink model. An optimization in the presence of demand response and wind power with real time pricing method is done in the RTPdemandwind file. The bnn2013anew simulink model is a model of AC grid with Dc load.
