Residential demand response from PV panel and energy storage device

This study proposes an optimal scheduling mechanism for residential appliances in a smart home equipped with photovoltaic panel and energy storage device. The optimal mechanism aims to manage the operation of centralized air conditioner, solar energy input and charging/discharging of energy storage device such that energy consumption cost is minimized. Mixed integer programming technique is applied to obtain optimal solution. For evaluating the effectiveness of proposed strategy, the results obtained from this technique are compared with previously established optimization technique using linear sequential algorithm in combination with price-aware storage algorithm. Results indicate that the proposed strategy have the capability of maximizing the savings in electricity cost. Contribution of this work is the introduction of a real time price based scheduling mechanism that utilizes smart grid capability of feeding power back to the grid.
