This document presents the modeling of load profile consumption for Low-and-Moderate-Income (LMI) communities in Caribbean Islands, as well an assessment solar-rooftop energy potential. In this work, real data, together with synthetic and electricity bill were collected to validate improve models. The potential was obtained through a National Renewable Energy Laboratory (NREL) software called P...

The aim of this article is to expand the general approach flexible beam model consider tapered geometry and anisotropic properties by updating cross-sectional stiffness matrix. advantage that continuously variable cross-section, as well irregular axes on cross-sections, are considered simultaneously co-rotational method. Anisotropic isotropic cantilevered cases simulated. A static force or mome...

With the large-scale development of wind turbines, large flexible blades bear heavier loads. In actual rotating work blades, coupling structural deformation and motion produces a dynamic stiffening effect spin softening effect, which affects characteristics blades. this study, finite element method is used to model NREL 5MW blade, effects are investigated using modal analysis. The influence on ...

This work is aimed at investigating the aero-elastic behavior of a wind turbine blade subjected to strong wind speeds during standstill. This type of investigation still remains a challenge for most wind turbine simulation codes. For this purpose, a new developed high fidelity framework for fluid-structure coupled computations of wind turbines is presented and numerical simulations are conducte...

A power production controller has been designed for the test turbine, which includes an independent individual pitch control (IPC) algorithm which can easily be switched in and out during operation. The turbine is already instrumented with well-calibrated blade root strain gauges, and by comparing test data with and without the IPC, the load reduction will be quantified. This is a 2bladed teete...

In this study, the effect of active induction control of upstream wind turbines is investigated. Two scaled wind turbines having a rotor diameter of 1 m with a spacing of four times of the rotor diameter were used to experimentally validate the concept. Also, an in-house c code was used to simulate the same two wind turbines and see if the experimental observations can be obtained. From the exp...

With increasing use of photovoltaic (PV) power generation by utilities and their residential customers, the need for accurate intra-hour and day-ahead solar irradiance forecasting has become critical. This paper details the development of a low cost all-sky imaging system and an intra-hour cloud motion prediction methodology that produces minutes-ahead irradiance forecasts. The SkyImager is des...

Due to the wind speed variation, wind shear and tower shadow effects, grid connected wind turbines are the sources of power fluctuations which may produce flicker during continuous operation. This paper presents a model of an MW-level variable speed wind turbine with a doubly fed induction generatorto investigate the flicker emission and mitigation issues. An individual pitch control (IPC) stra...

Hybrid energy systems such solar and wind energy in combination with diesel generator can be applied successfully in areas where grid connection is not available or considered uneconomical. Their costs can be minimized through proper equipment sizing and load matching. This study represents the cost analysis of various models of hybrid systems for powering a remote area telecom tower located at...
