چکیده مقاله :
امروزه استفاده از منابع تولید پراکنده به‌صورت متصل به شبکه رشد چشم گیری دارند، لذا مبدل‌های متصل به شبکه باید قابلیت خدماتی فراتر از تزریق توان به شبکه، از جمله حفظ پایداری شبکه را داشته باشند. در این مقاله استراتژی کنترل و مدیریت انرژی برای باتری، باد، فتوولتائیک و دیزل متصل به شبکه سه فاز با فعال کردن محدودیت جریان تحت خطاهای نامتعادل معرفی شده است. در این روش، جریان های تزریق شده به مقدار معین در طول خطاها محدود می شود. همچنین حالت عملکرد بدون ردیابی حداکثر نقطه توان (MPPT)برای مبدل نیز لحاظ شده است، این حالت در خطاهای شدید، زمانی که مبدل نمی تواند حداکثر توان سیستم را کنترل کند فعال می شود. لذا در ریزشبکه با وجود یک کنترل کننده ناظر مبتنی بر منطق فازی، عمل کنترل مبدل dc به dc دوطرفه باتری و مدیریت منابع تولید پراکنده انجام می شود. همچنین از کنترل کننده تناسبی رزونانسی به دلیل عملکرد مناسب آن، در این کار استفاده می شود. در حقیقت با استفاده از تولید جریان مرجع، جریان سینوسی با مقدار اعوجاج هارمونیک کل (THD) کمتر از 5 درصد تزریق می شود. نتایج نشان می دهد که استراتژی کنترلی همراه با مدیریت انرژی با چندین منبع تولید انرژی، اولاً قادر است که با وجود خطای نامتقارن در شبکه بالادستی، ولتاژ لینک dc را در یک بازه قابل قبول حفظ و جریان خطا را محدود کند لذا عملیات عبور از خطا بدون عملکرد رله های حفاظتی به‌درستی انجام شده است و ثانیاً در مقایسه با ریزشبکه با حضور فقط یک منبع تولید فتوولتائیک، روند تزریق توان اکتیو و راکتیو در شبکه بالادستی مطلوب‌تر است.
Today, the use of distributed generation resources connected to the network has remarkable growth therefore network-connected to the converters must be able to provide services beyond the injection of power into network, including maintaining network stability. In this paper the control and management of energy for battery wind, photovoltaic and diesel connected to a three-phase network by activating the current limitation under unbalanced fault has been introduced. In this method injected currents are limited to a certain amount along the faults Also, the operation mode without tracking the maximum power point for the converter is included. This state is activated during severe faults, when the converter cannot control Maximum power of the system. Therefore, in a microgrid with, the operation of a fuzzy logic-based controller the transformation operation of DC to DC converter control is performed sparsely by two-way battery and distributed generation resources management. Also proportional resonance controller is used due to its proper performance. In fact, with the use of reference current generation, sinusoidal current with a total harmonic distortion (THD) value of less than 5% is injected. The results show that the control strategy along with energy management with multiple energy generation resources is able to limit and maintain DC link voltage within an acceptable range in addition to The existence of an asymmetric fault. Therefore, the fault crossing operation has been performed correctly without the operation of the protection relays and secondly in comparison with microgridsolely with the presence of one photovoltaic production source the process of injecting active and reactive power in the upstream network is more appropriate.
