A hybrid approach for optimal energy management system of internet of things enabled residential buildings in smart grid

Abstract

Nowadays, a large number of smart devices in residential buildings is integrated with the evolution of internet of things (IoT), where it is necessary to effectively manage energy to meet the increase in demand. Therefore, in this paper, an optimal energy management strategy using the hybrid Gradient Boosting Decision Tree ‐Artificial Transgender Longicorn Algorithm (GBDT‐ALTA) is proposed for IoT‐enabled residential buildings. The main objective of the proposed approach is to minimize the electricity bill of customer, thereby Peak‐to‐Average Ratio (PAR) is reduced. Due to the scheduling process of residential electric devices, the proposed approach utilizes the waiting time threshold. Here, three types of appliances, such as shiftable electrical devices, thermostatically controlled electrical devices, and generally operated electrical devices are considered. Related to real‐time price signals (RTPS) in utilities, scheduling the shiftable electrical devices is processed. The cost minimization with less acceptable time of waiting is achieved by GBDT‐ATLA method, which considers the trade‐off between the electricity cost and waiting time. Moreover, the proposed approach maintains the stability of the grid, because the stability of grid depends on the PAR. The proposed method is carried out in MATLAB/Simulink site and the simulated results prove that the better performance of GBDT‐ATLA approach compared to the existing approaches, like Slime Mould Optimization (SMO), Chaos Game Optimization Algorithm (CGO), and Side‐Blotched Lizard Optimization Algorithm (SBLO). The efficiency of the proposed approach under 100, 200, 500, and 1000 trails are 99.7300%, 99.6513%, 99.8363%, and 99.7916% respectively.

Integrated Energy Management of Smart Grids in Smart Cities Based on PSO Scheduling Models

“…The model assumes that the water heater operates in the on/off state, and if the operating state S EWH t of the water heater during time slot t is 1, the power consumption of the water heater is equal to the rated power P EWH , otherwise it is 0. During the scheduling interval, the hot water temperature is maintained within the user's preset range, as shown in Equation (7).…”

“…HEMS responds to information such as time-of-use tariffs and reasonably implements demand side management, reducing residential electricity costs, smoothing the load curve, and improving power system security [6]. Based on the time-sharing tariff, a decision model for optimal operation of household equipment is established with the objective of minimizing the peak-to-valley load difference [7]. For the volatility and randomness of distributed power supply, the control strategy of flexible load in the object being supplied is studied, and the charging and discharging of energy storage equipment are controlled.…”
