Dynamic Optimal Power Flow on Microgrid Incorporating Battery Energy Storage Considering Operational and Maintenance Cost

Renewable energyEnergy is currently used to overcome fossil fuel problems. The existence of renewable energyEnergy provides a role for ordinary people to produce energyEnergy through the installation of photovoltaicPhotovoltaic and wind turbinesTurbine. PhotovoltaicsPhotovoltaic can only have maximum power for about 3 to 4 h in Surakarta, Indonesia. The maximum energyEnergy is distributed to the load, and the excess energyEnergy is stored in the energyEnergy storage batteryBattery. The cost incurred by renewable energyEnergy generation is nonexistent. However, in this modeling, renewable energyEnergy generation costs are taken from the operational and maintenance (O&M) costs per year. This consideration will represent the optimal cost approach under actual conditions. The system in this paper uses microgrid modeling based on a modified IEEE 30 Bus system. The microgrid is connected to the utility grid and batteryBattery system, the 2nd and 3rd parties. Optimal Power Flow and Mixed Integer Non-Linear Programming are used to obtain the most minimal cost that the system can incur. The result of the cost comparison with and without considering O&M cost shows that the cost to be incurred by microgrid is higher than about 12.328% when considering O&M cost. However, these costs may represent a more accurate cost approach.
