A demand response (DR) based home energy management systems (HEMS) synergies with renewable energy sources (RESs) and energy storage systems (ESSs). In this work, a three-step simulation based posteriori method is proposed to develop a scheme for eco-efficient operation of HEMS. The proposed method provides the trade-off between the net cost of energy (
) and the time-based discomfort (
) due to shifting of home appliances (HAs). At step-1, primary trade-offs for
and minimal emissions
are generated through a heuristic method. This method takes into account photovoltaic availability, the state of charge, the related rates for the storage system, mixed shifting of HAs, inclining block rates, the sharing-based parallel operation of power sources, and selling of the renewable energy to the utility. The search has been driven through multi-objective genetic algorithm and Pareto based optimization. A filtration mechanism (based on the trends exhibited by
in consideration of
) is devised to harness the trade-offs with minimal emissions. At step-2, a constraint filter based on the average value of
is used to filter out the trade-offs with extremely high values of
. At step-3, another constraint filter (made up of an average surface fit for
) is applied to screen out the trade-offs with marginally high values of
. The surface fit is developed using polynomial models for regression based on the least sum of squared errors. The selected solutions are classified for critical trade-off analysis to enable the consumer choice for the best options. Furthermore, simulations validate our proposed method in terms of aforementioned objectives.
