Dear Sir, I try to simulate a hybrid wind-photovoltaic system where electric energy is stocked in a battery. I linked the sum of outlet power from both Wind and PV units to a regulator, which is connected to the battery. However, I find that, at each instant, the power of battery (Output 3 in Type 47) is equal to the sum mentioned above and that there is no storage of free electrical energy. In addition, I would like to note that the battery state of charge increases with time. Thank you for your help. Best Regards Farah |
