Integrated optimal design and sensitivity analysis of a stand alone wind turbine system with storage for rural electrification

Abstract

In this paper, the authors investigate a robust Integrated Optimal Design (IOD) devoted to a passive wind turbine system with electrochemical storage bank: this stand alone system is dedicated to rural electrification. The aim of the IOD is to find the optimal combination and sizing among a set of system components that fulfils system requirements with the lowest system Total Cost of Ownership (TCO). The passive wind system associated with the storage bank interacts with wind speed and load cycles. A set of small power passive wind turbines spread on a convenient power range (2-16 kW) are obtained through an IOD process at the device level detailed in previous papers. The system cost model is based on data sheets for the wind turbines and related to battery cycles for the storage bank. From the range of wind turbines, a "system level" optimization problem is stated and solved using an exhaustive search. The optimization results are finally exposed and discussed through a sensitivity analysis in order to extract the most robust solution versus environmental data variations among a set of good solutions.

Hybrid renewable energy supply for rural healthcare facilities: An approach to quality healthcare delivery

“…Furthermore, the techno-economic analysis of stand-alone hybrid photovoltaic-diesel-battery systems for rural electrification in eastern part of Iran has been presented [23]. A study has been discussing which focuses on the integrated optimal design and sensitivity analysis of a standalone wind turbine system with storage for rural energy supply [24]. The techno-economic feasibility analysis of a solar-biomass off-grid system has been discussed, with focus on the electrification of remote rural areas in Pakistan using HOMER software [25].…”

“…[5, 14, 20-23, 25, 26] do not consider battery analysis, while the CO 2 emissions analysis is not considered in the papers in Refs. [20,21,[24][25][26]. It is of interest in this paper to cover the gaps identified in the mentioned studies by presenting a detailed simulation and analysis that includes the battery state-of-charge evalaution in the technical design, coupled with the economic and the CO2 emissions analyses.…”

How Hybridization of Energy Storage Technologies Can Provide Additional Flexibility and Competitiveness to Microgrids in the Context of Developing Countries

“…As described in reference [35], the rainflow algorithm is a widely used model [36][37][38][39][40][41][42][43][44][45], usually applied to evaluate battery lifetime when subjected to complex cycles, as in the case of the present investigation. Even if it is not accurate, generally providing an overestimated lifespan evaluation, this strategy was here implemented since the authors were interested in a lifespan comparison among several storage configurations rather than to achieve an absolute estimation of battery useful life.…”

Mitigation of Power Quality Issues Due to High Penetration of Renewable Energy Sources in Electric Grid Systems Using Three-Phase APF/STATCOM Technologies: A Review

“…At the distribution level, STATCOM devices are operated as an active filter to achieve harmonic filtering, power factor correction, neutral current compensation, and load balancing [39]. APFs are an advanced technology that offers faster dynamic response, smaller size, lower system cost, and higher performance under low-voltage oscillations than SVC devices.…”
