Enhancing Smart Grid realisation with accurate prediction of photovoltaic performance based on weather forecast

The energy conversion efficiency of photovoltaic (PV) panels depends on solar irradiance and cell temperature. The cell temperature is affected by ambient and sky temperature, wind speed and direction, in addition to solar irradiance. This study summarises relevant relationships in the literature and describes a method of calculating cell temperature and efficiency, based only on field-measured solar irradiance, ambient temperature and wind speed. These equations have been applied to a 500?kW PV site on a typical spring day and all results were within 1.6% of measured values, with an average error of 0.05%. This provides a predictive capability for solar PV to be efficiently integrated into a Smart Grid.

Design,construction and performance prediction of integrated solar roof collectors using finite element analysis

An integrated roof solar collector was designed to achieve ease of construction, energy efficiency, functional integration, composite behavior, sustainability, reliability, flexibility, and cost effectiveness. A construction strategy was developed for the collector to ensure quality, ease and repeatability of manufacturing. Three-dimensional (3D) finite element models were then developed to evaluate the thermal performance of the integrated roof solar collector. The models were used to predict the optimum set of variables that can be used in buildings to achieve adequate thermal comfort. Coupled conduction, forced convection, and long wave thermal radiation modes of heat transfer were considered in the developed models. For demonstration purposes, a specific location (Blacksburg, VA) was modeled. Results showed that the integrated roof collector provides acceptable thermal performance by supplying approximately 85% of the building space heating and hot water requirements.

The challenging economics of US residential grid defection

Declining costs for solar photovoltaics (PV) and excitement about new technologies have led to speculation that self-sufficient PV/battery storage systems will soon become competitive with traditional electricity service. We compare a grid-tied residential solar system with an off-grid solar-plus-battery system at 1020 US locations, and calculate three effects of “grid defection” for each: the private net costs to the homeowner, the change in system generation costs, and change in system emissions. For the average US location, an off-grid solar system is almost double the price of grid-connected solar, is associated with higher system generation costs, and has no emissions benefit.     

Harnessing technology in collaborative renewable energy education

ABSTRACT

A state-of-the-art eLearning renewable energy course, which consists of a number of topics and a practical component with several experiments, has been designed to showcase the paradigm for reform and modernisation of engineering curriculum in Jordan. The online experiments were physically distributed in four universities that cover most of the geography of the country. The experiments can be conducted by students over the internet at any time from anywhere by any student in the country. The eLearning course was piloted and delivered to students jointly in four universities over a period of two years. The experiments encompassed topics on wind and solar photovoltaics power generation, solar tracking control, hybrid energy and fuel cells. The teaching effectiveness from the perspective of the students was investigated and feedback from faculty members, technicians and students supporting the delivery of the courses was explored. The results actually show a promising endorsement by students of this innovative approach and demonstrate clearly their passion for reform, renovation and novelty. The new model for the online course may be integrated into the corresponding curriculum and engineering study plans as its evaluations by both professors and students were found significantly favourable.
