Off-line and On-line Power Dispatching Strategies for a Grid Connected Commercial Building with Storage Unit

With the development of decentralized power sources based on renewable energy, power grids need smarter operations to be run properly. This paper refers to a microgrid with solar panels associated with an energy storage unit connected to the main grid. An off-line optimal dispatching of the storage power flows is proposed in order to minimize energy costs with regards to the daily energy rates. An on-line management strategy is also introduced so as to control in real-time the grid power predicted over the day by the off-line dispatching
