Abstract

Advances in non-conventional energy technologies and increasing fossil fuel prices along with environmental concerns have made hybrid renewable energy systems important. In view of this scenario, solar panel mounted on a vertical axis wind turbine (called as solar-wind tower) can be utilized to produce more electric energy than individual one. This solar-wind tower will be located in the space available between two opposite roads of expressways/highways. Solar-wind tower located in such a manner that the air velocity produced from driving vehicles on both sides of the road is adequate to cut the turbine blades which will produce unidirectional torque. A battery energy storage system (BESS) stores the power produced by the solar-wind tower so that it can subsequently be used for local loads and electric vehicle charging stations (EVCS) and remaining energy can be supplied to the grid. In this work, a hybrid system composed of wind and solar is designed and modelled in Simulink (MATLAB) and tested on real data of wind speed and validated by Opal-RT simulator. From the simulation result, it is estimated that total electrical power output of a single solar-wind tower is around 15 to 20 kWh in a day under the assumed conditions.

用于电动汽车充电的太阳能-风能混合发电塔的估算:印度高速公路案例研究
非常规能源技术的进步、化石燃料价格的上涨以及对环境的担忧,使得混合可再生能源系统变得非常重要。在这种情况下,安装在垂直轴风力涡轮机(称为太阳能风力塔)上的太阳能电池板可以比单个太阳能电池板产生更多的电能。该太阳能风塔将位于快速路/高速公路两条相对道路之间的空地上。太阳能风塔的位置应使道路两侧车辆行驶时产生的气流速度足以切割涡轮叶片,从而产生单向扭矩。电池储能系统(BESS)可储存太阳能风塔产生的电能,以便随后用于本地负载和电动汽车充电站(EVCS),并将剩余电能供应给电网。在这项工作中,设计了一个由风能和太阳能组成的混合系统,并在 Simulink(MATLAB)中进行了建模,在真实风速数据上进行了测试,并通过 Opal-RT 模拟器进行了验证。根据模拟结果估计,在假设条件下,单个太阳能风能塔一天的总发电量约为 15 至 20 千瓦时。
