Energy cost reduction in residential nanogrid under constraints of renewable energy, customer demand fitness and binary battery operations

Intermittence of renewable energy is a challenge to demand side management in distributed grid technologies. Time-of-use tariffs are often applied to implement traditional strategies such as peak shaving and valley filling that are more functional to conventional grids. Time-of-use tariffs are howev...

description Intermittence of renewable energy is a challenge to demand side management in distributed grid technologies. Time-of-use tariffs are often applied to implement traditional strategies such as peak shaving and valley filling that are more functional to conventional grids. Time-of-use tariffs are however not suitable to matching customer demands as the periodic charges are fixed and cannot be match with stochastic renewable power generations. This paper proposes a time-of-use fitness in a grid connected photovoltaic/wind/battery nanogrid for energy cost reduction and maintained customer comforts. The proposed method considers three configurations of the nanogrid optimized using nested integer linear programming. Fitness functions are applied to either critical or flexible demands based on real-time residential consumptions, renewable generation and main grid imported power.
