# Maximizing Efficiency in Energy Trading Operations through IoT-Integrated Digital Twins
## 3 Proposed Architecture  
This section establishes a system for energy trading within nano-grids using a digital twin and task coordination based on the Internet of Things (IoT). The primary concept revolves around using sensors and the Internet of Things (IoT) to effectively oversee the energy trading procedure within nano-grids, diminishing the expenses associated

with the upkeep of tangible resources. The proposed methodology encompasses two primary components: the enhancement of energy storage systems for residential units within the nano-grid that engage in peer-to-peer energy exchange and the virtual execution of the complete energy trading procedure through the Internet of Things (IoT)-based task coordination to reduce expenses associated with tangible resources, such as solar panels and energy storage batteries. The architectural representation of this system is depicted in Figure 2. The initial step involves collecting input data about each module within the nano-grid. This includes information on energy consumption, energy storage system (ESS) data, energy load, energy generation from solar panels (photovoltaic or PV), electricity costs, and relevant photovoltaic details. The aforementioned data are sent to the prediction module, which employs a prediction technique based on gated recurrent units (GRUs) to anticipate energy load, photovoltaic (PV) generation, and energy consumption. Before producing predictions, it is imperative to analyze the input data thoroughly. Subsequently, a subset of these forecasts is utilized within the energy trading module to effectively optimize the energy costs.

The proposed design incorporates the concept of a digital twin, consisting of two primary components: the \"virtual space\" and the \"physical space\". Within virtual environments, the preliminary stages of task management encompass several activities, including creating tasks, generating virtual representations of devices, formulating task schedules, and allocating those tasks. In contrast, the physical space encompasses the virtual resources utilized for the efficient execution of tasks.
