Embedded solution for data acquisition and management strategy dedicated to a hybrid renewable energy source for remote electricity supply

Abstract

Electrifying people using renewable energy is a promising alternative that is gaining increasing importance for remote areas needs, but this solution is quite sensitive to the intermittent nature of environmental data, which puts more strain on the designer to overcome these problems to surely electrify consumers. In this work, the authors tackle a key topic of energetic and environmental data acquisition and energy management for electrifying a typical remote zone using a hybrid photovoltaic-wind system associated to an electrochemical storage system. An innovative alternative for data acquisition and intelligent on-board management of this system based on a Raspberry PI programmable target is presented. The first part of this article outlines the photovoltaic-wind turbine-batteries generation system architecture. The data acquisition and energy management methodology is described in the second part of this article. The results are finally discussed from the point of view of the suitability of the proposed embedded solution.
