摘要

本文介绍了一种动态智能家居能源管理系统（SHEMS），该系统集成了混合光伏（PV）和重力储能（GES）系统，旨在最大限度地减少对环境的影响和家庭能源消耗。新型 SHEMS 具有一周动态预测模型，可适应可变电价、智能家电计划、太阳能输出和储能状态。这些结果表明，该系统不仅降低了家庭能源使用量，还大幅减少了电费支出，每天可自主供电长达 8.5 小时。通过利用来自黑暗天空应用程序接口（Dark Sky API）的云层和温度实时数据，该模型可以准确预测太阳辐射和光伏发电量，使其与电网和居民需求保持一致。预测精度采用均方根误差（RMSE）和平均绝对百分比误差（MAPE）进行评估，从最初的均方根误差（RMSE）22.46% 和平均绝对百分比误差（MAPE）11.78% 分别提高到 12.55% 和 4.91%。这些进步增强了电网的稳定性，优化了高峰期的能源存储，减少了对化石燃料的依赖。创新的可再生能源技术与复杂的预测建模相结合，大大提高了系统的效率，促进了能源的可持续利用，实现了环境和经济目标。

Hybrid photovoltaic and gravity energy storage integration for smart homes with grid-connected management

This paper introduces a dynamic Smart Home Energy Management System (SHEMS) integrating a hybrid photovoltaic (PV) and gravity energy storage (GES) system aimed at minimizing environmental impacts and household energy consumption. The novel SHEMS features a one-week dynamic forecasting model that adapts to variable electricity prices, smart appliance schedules, solar output, and energy storage states. These results demonstrate that the system not only reduces household energy usage but also cuts electricity bills significantly, supplying power autonomously for up to 8.5 hours daily. By leveraging real-time data from the Dark Sky API on cloud cover and temperature, this model accurately predicts solar radiation and PV generation, aligning it with both grid and residential demands. The forecasting accuracy was assessed using Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE), which improved to 12.55% and 4.91% respectively, from initial values of 22.46% for RMSE and 11.78% for MAPE. These advancements enhance grid stability and optimize energy storage during peak periods, reducing dependence on fossil fuels. The integration of innovative renewable energy technologies and sophisticated forecast modeling significantly boosts the system's efficiency, promoting the sustainable use of energy resources in line with environmental and economic goals.
