GUI-Based Secure Architecture Design for Distributed Community Micro-grid

Power generation from solar photovoltaic (PV) plants depends on multiple factors such as solar radiance and ambient temperature. Effective monitoring and control of the energy generated with the solar PV plants may augment the complete performance of the system. The local controllers regulate switching between solar PV, local battery, community battery, and grid according to the availability of power in each system. The sensor data and user information are stored in the cloud that can be accessed with the Internet of Things (IoT) device for further computation. A Web-based graphical user interface (GUI) has been developed for appropriate monitoring and control of energy flow and also to enable the power pooling. The app gets information from the cloud on which various sensor’s data regarding energy pooling are stored by the local/community controllers, and it displays the information that is stored in the cloud. The primary task is to design and develop a Web-based application with sufficient data security. To secure the user data in the cloud, multi-factor authentication and symmetric key encryption are used for authorized access and data encryption. The basic model of the Web-based application is presented in this paper.
