Scheduling energy storage unit with GWO for smart home integrated with renewable energy

The paper proposes a novel swarm-based grey wolf optimiser (GWO) algorithm to optimally schedule the energy storage unit for a smart home integrated with the renewable energy resources such as wind and solar. The proposed method does not impose any restrictions regarding when to use appliances and ensures that all the household demands are met any time of the day. It reduces the cost of energy consumption for the user and at the same time balances the load on the grid by drawing less energy from the grid when the demand is high. Whenever the renewable energy resources are generating power, they are used for meeting the demand and to charge the ESU. The excess power generated is sold back to the utility at the same hourly price. The GWO was tested using data obtained from the United States Department of Energy for Chicago and outperformed PSO.
