Optimizing Home Energy Management: Genetic Algorithm for Effective Load Scheduling and Cost Reduction.

Problem Definition

From the literature survey conducted, it is evident that the current state of Home Energy Management Systems (HEMS) faces several limitations and challenges. One of the key problems identified is the need to reduce electricity costs and Peak-to-Average Ratio (PAR) values through optimization techniques. However, the selection of an ideal optimization algorithm poses a major hurdle for researchers due to the plethora of options available. Existing algorithms often suffer from issues such as slow convergence rates and getting trapped in local minima, leading to increased complexity in the modeling process. Furthermore, a lack of priority mechanisms in current HEMS results in inefficient device operation, with higher priority devices having to wait for their designated time slots.

Additionally, the impact of erratic weather conditions on load scheduling has not been extensively studied, highlighting a critical gap in the existing research. These limitations underscore the necessity of developing a new and effective HEM system that can address these challenges and provide improved solutions for optimizing electricity usage and managing household energy consumption efficiently.
