TIDAL ENERGY: THE CASE OF EURIPUS’ STRAITS
The tidal energy potential of low current tidal and marine currents is investigated in this work. Existing data on the current velocity and sea level at the Euripus’ strait in Evia, Greece, is used to compute the energy yield based on contemporary turbine designs. Requirements, limitations and opportunities concerning the exploitation of low velocity tidal streams are discussed. The exploitation of tidal energy technology in conjunction with RES microgrids is proposed for coastal areas with abundance of sun and wind such as the Mediterranean islands

GAMIFYING ENERGY USER PROFILES
Smartege is an educational application which aims in educating users in the basics of electrical energy consumption and production and engage them in energy saving behavior, techniques and technologies. This is accomplished through the virtual, and eventually actual, management of residential and office buildings equipped with virtual devices and renewable energy sources, with energy specifications borrowed from actual commercial devices, towards the ultimate target of transforming the buildings into net Zero Energy Buildings. Ultimately, Smartege is a gamified application targeting the behavior modification of the users. Its content development follows the persuasive model and uses cognitive learning for the educational component and game mechanics for user motivation and triggering

Machine Learning Platform for Profiling and Forecasting at Microgrid Level
The shift towards distributed generation and microgrids has renewed the
interest in forecasting algorithms and methods, which need to take into
account the advances in information, metering and control technologies
in order to address the challenges of forecasting problems. Technologies
such as machine learning have been proven useful for short-term
electricity load forecasting, especially for microgrids, as they can
also take into account several types of historical data and can adapt to
changes often encountered in small-scale systems and on a short time
scale. In this paper, we present a flexible and easily customized
modular toolbox, called Divinus, for electricity use profiling and
forecasting in microgrids. Divinus may support a variety of machine
learning algorithms for forecasting and profiling that can be used
independently or combined. For demonstration purposes, we have
implemented Self-Organizing Maps for profiling and k-Neighbors for
forecasting. The testing of the platform was based on electricity
consumption data of the Euripus campus of the National and Kapodistrian
University of Athens in Evia, Greece, from January 2010 till March 2018.
The tests that have been carried out so far show that the platform can
be easily customized and the algorithms examined yield high accuracy and
acceptable mean errors for the case of a university campus energy
profile
