The turn of the 21st century has seen a positive change in the attitude towards sustainable energy. The focus on awareness and implementation of renewable energy has improved. However, it is also important to study the energy usage. Demand Side Management (DSM) and Demand Response (DR) are not new ideas. They were introduced during the 1970s when the world was rife with energy crises. However, with population growth, increased dependence on electricity and introduction of renewable energy, these ideas are more relevant than ever. One of the biggest problems energy systems face is their efficiency. DSM and DR provide a viable solution to increase energy efficiency by reducing the peak demand and improving the demand and supply. HVAC systems generally prove to be the highest consumers of electricity. In this study, the efficiency of cooling systems is improved by setting the setpoint temperature based on an adaptive thermal comfort model in Middle East Technical University Northern Cyprus Campus and its effect on the demand is studied. The cases considered are based on the setpoint being controlled at all times, setpoint control on a schedule, setpoint control when demand peaks and setpoint control based on when demand exceeds an aggregate forecasted demand. Furthermore, this is employed in conjunction with PV systems with net metering to shift loads to periods with lower demand from the grid to improve grid stability. It is found that when setpoint is controlled at all times, energy consumption from cooling systems is cumulatively reduced by 55.7% for May, July, September and October with a minimum peak demand decrease of 1.55% for October, while when setpoint control is employed only when demand rises above the aggregate forecasted demand, the energy consumption by cooling systems is reduced by 30.3% cumulatively for May, July, September and October with a minimum peak demand decrease of 1.55% for October. Furthermore, with the cooling system improvements and PV system load shift, the peak demand reduction increases to 10.46% for October. Moreover, for winters, which have a comparatively higher rise in peaks, due to lower demand during the day, load shifting using PV decreases the peak demand by 25%, 18% and 14% for November, December and January respectively.

Solar irradiation on the rear surface of bifacial solar modules: a modeling approach Durusoy, Beyza; ÖZDEN, TALAT; Akınoğlu, Bülent Gültekin (Springer Science and Business Media LLC, 2020-08-01) The transition in the energy sector has started with the growing population leading to the growing energy demands. The use of photovoltaic (PV) technologies has become a crucial way to meet energy demand. There are many ongoing studies for increasing the efficiency of commercial PV modules. One way to increase the energy yield of the PV modules is to use bifacial solar panels by capturing the rear side illumination as well. One of the challenges for estimating the bifacial module performances is to calculat...
Smart Solar Micro-grid Using ZigBee and Related Security Challenges Qadir, Zakria; Tafadzwa, Vincent; Rashid, Haroon; Batunlu, Canras (2018-11-02) Renewable energy is needed to preserve a sustainable environment. One particular form of renewable energy (solar energy) is one of the most important and cost-effective solutions to the energy crisis. In this study, efficient solar energy management using ZigBee technology shall he discussed. The system informs the user when solar panels produce excess power before supplying it to the surrounding users, thus making the supplier a prosumer instead of a consumer. GSM which is used to monitor energy usage over...
Data Mining-Based Upscaling Approach for Regional Wind Power Forecasting: Regional Statistical Hybrid Wind Power Forecast Technique (RegionalSHWIP) Ozkan, Mehmet Baris; Karagöz, Pınar (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01) With the increasing need for the energy, the importance of renewable energy sources has also been increasing. In order to include the power produced by the wind into electricity grid in a controlled manner, power prediction has an important role. To produce a reliable wind power forecast, obtaining Wind Power Plants' (WPP) power generation data in real time and constructing the power forecast model with historical production values is a desirable action plan. However, this situation may not be applicable fo...
Comminution: Technology, Energy Efficiency and Innovation Klein, B.; Altun, Naci Emre; Scoble, M. J. (2015-04-17) With pressures to improve energy efficiency in mining, reducing energy usage in comminution has become the focus of innovation. Several advances have been made however the uptake of innovations and technologies is slow. A Technology Readiness Level guide has been developed for other industries that may be a useful tool for the mining industry. Examination of selected successful energy efficient technologies provides some insights and lessons that may provide direction for advancing new technologies. This pa...
Modelling, simulation and trajectory control of an airborne wind energy system for wind power generation Rashid, Muhammad Rameez; Prach, Anna; Sustainable Environment and Energy Systems (2022-9-1) Significant progress is being made in developing creative and cost-effective technologies to reduce our dependence on fossil fuels and enable the transition toward renewable energies. Airborne Wind Energy (AWE) systems refer to the generation of useable power by airborne devices such as kites, wing gliders, parafoils, and drones. They can reach higher altitudes and leverage an abundant and previously unused wind resource than a conventional wind turbine. On the other hand, they need far less material to tra...
