چکیده مقاله :
از جمله مسائل مهم و در عین حال نگران کننده، آلودگی های زیست محیطی و هدررفت منابع انرژی فسیلی است. به منظور کاهش گازهای گل خانه ای و آلودگی هوای ناشی از مصرف سوخت های فسیلی، استفاده از خودروهای برقی امری ناگزیر به نظر می رسد. با افزایش روزافزون خودروهای برقی و درنتیجه تحمیل بار بیش تر به شبکه قدرت، ارائه روشی جدید به منظور کنترل ولتاژ و مدیریت شارژ و دشارژ خودروهای برقی و حداقل سازی تلفات شبکه ضروری است. با این وجود، اجتماع خودروهای برقی در یک سیستم تجمیع کننده و انرژی حاصل از باتری های آنها، یک منبع عظیم ذخیره انرژی را فراهم می نماید. هماهنگی و کنترل مناسب شارژ و دشارژ خودروهای برقی براساس تکنولوژی خودروبرقی به شبکه (V2G)، نه تنها می تواند اثرات نامطلوب ناشی از افزایش نفوذ خودروهای برقی را به حداقل برساند بلکه می تواند سبب بهبود پروفیل ولتاژ شبکه نیز شود. در این مقاله، به منظور کنترل کمیت های متغیر تولید و مصرف، یک الگوریتم جدید با تابع هدف متغیر پیشنهاد شده است. در روش پیشنهادی کنترل ولتاژ نقطه اتصالی (PCC) و مدت زمان شارژ/دشارژ در یک بازه معین، که بستگی به شرایط عملکردی مختلف دارد، به عنوان تابع هدف قابل تغییر در نظر گرفته شده است. همچنین، محدودیت هایی برای وضعیت شارژ (SOC) باتری خودروهای برقی در نظر گرفته شده است. کاهش تلفات شبکه در پیک بار و ایجاد هماهنگی مناسب بین شارژ و دشارژ که منجر به شارژ کامل خودروهای برقی در انتهای سیکل شارژ می شود، از دیگر مزایای استفاده از روش پیشنهادی هستند. شبیه سازی ها برای یک سیستم توزیع 14 باسه IEEE مجهز به تکنولوژی خودروبرقی به شبکه براساس الگوریتم تابع هدف متغیر (VOF) پیشنهادی برای هر دو حالت شارژ و دشارژ با استفاده از نرم افزار شبیه سازی متلب انجام یافته و برای سناریوهای مختلفی ارائه شده است. در نهایت، نتایج حاصل از روش پیشنهادی با نتایج روش مرسوم مقایسه شده و برتری عملکرد آن به اثبات رسیده است.
The use of electric vehicles (EVs), to reduce greenhouse gases and air pollution caused by the fossil fuel consumption, seems to be an inevitable solution. The increased penetration of EVs imposes a large variable load to the grid. However, the battery of EVs in an aggregator provides a large source of energy storage. Therefore, EVs depending on the charging or discharging modes can act as flexible loads or as flexible energy sources. Then, the proper coordination and control charging and discharging of EVs, using vehicle-to-grid (V2G) technology, not only can minimize the undesirable effects resulting from the increased penetration of EVs, but also can improve the voltage profile. In this paper, a new algorithm with variable-objective function is proposed to control variable quantities of generation and consumption. In the proposed method, the control of the point of common connection (PCC) voltage in a specific value of a determined permissible range, which depends on different operating conditions, can be considered as a variable-objective function. Moreover, there are constraints to state of charge (SOC) of electric vehicles (EVs) batteries and charging/discharging time. Other advantages of using the proposed method are the reduction of network losses in peak load hours and the establishment of an appropriate coordination between charging and discharging EVs. The simulations of the IEEE 14-Bus distribution system with V2G capabilities based on the proposed variable-objective function (VOF) algorithm are implemented for both charging and discharging modes using MATLAB/PSAT software and tested for the various scenarios. Finally, the results of the proposed method are compared with the traditional method and the merit of that is proved.
