Iran's economy has always been under severe sanctions. These sanctions were almost tolerable for Iran since they did not affect Iran's oil industry which is the main source of foreign currency for the country. The recent sanctions on Iran's oil-dependent economy starting from 2012, put a lot of pressure on the country and the overall country experienced very volatile conditions. As the result, the...
The prevalence of distributed energy resources (DER) presents challenges to traditional utility metering schema. Energy consumption and demand are valuable data when planning the size and growth of electrical systems from a reliability perspective. Some utilities meter the output of the DER inverters, in order to provide generation data to the customer and adequately plan for reliability. A DER solution...
Fault current contribution of Renewable Distributed Generation (DG) has become a major concern in present power industries. Installation of DG not only alters the load flow in the distribution network but can also affect the fault current during a grid disturbance. The effect of DG integration on a system can be investigated for two different types of DG: Inverter based DG (IBDGs), and Non-Inverter...
A solar simulator has been designed, built and characterized for the purpose of laboratory testing of Solar Panels. The solar simulator has been developed using off the shelf Xenon, Halogen and LED bulbs. The light bulbs were organized in such a way so that they approximate the luminous intensity and the spectrum of the sun. The solar simulator is intended to be used by students for the Renewable...
The recovery of biomass using flocculation is a procedure economically viable, however, it may cause damage to the cells and loss of the metabolic product of interest, such as lipids, according to the flocculant used and its concentration. In this work, different flocculants were evaluated for the flocculation of microalgae biomass of Acutodesmus obliquus, aiming to achieve a biomass recovery efficiency...
Photovoltaic module performance is defined at standard test conditions, which includes a defined spectral irradiance distribution. However, environmental conditions in the field often differ from the standard spectrum; this change in spectrum is known as spectral shift or spectral mismatch. This paper discusses the impact of spectral shift on various PV technologies and presents models that have been...
Demand Response (DR) is a great way to save energy and revenue, it could be beneficial to both consumers and the utility companies. Aggregating residential houses and then analyzing DR on these can help understand and manage DR better. Aggregation can also help the utilities understand the patterns of electrical consumption for a geographical region, area, community. This pattern learning process...
The conditions for cultivation of microalgae Phaeodactylum tricornutum were studied with the objective of increasing algae lipid content for the production of biodiesel aiming at renewable energy generation. The variables investigated in the experiments were: salinity, carbon source (glycerol and glucose) and photoperiod. From the growth kinetics, and the analysis of biomass and lipid production,...
It is shown that a record power conversion efficiency (PCE) of 1.25% can be obtained through coating reduced graphene oxide/n-silicon (rGO/Si) solar cell with silver nanowires (Ag NWs) and subsequently GO. rGO/Si solar cells were obtained through one step spin coating of GO on patterned n-silicon wafer followed by thermal annealing in an inert environment. Ag NWs were employed to reduce the sheet...
