در این مقاله روشی جدید برای تشخیص خطا و تعیین محل خطا در ریزشبکۀ سولار MTDC ارائه شده است. مسائلی از جمله گسترش منابع تولیدات تجدیدپذیر و بارهای DC و تلاش برای افزایش کیفیت توان و کاهش اثرات زیست‌محیطی تولید برق باعث گسترش شبکه‌های سولار شده است. تشخیص انواع و محل خطا برای تداوم سرویس‌دهی و جلوگیری از خرابی بیشتر و تقویت ویژگی انتخابگری حفاظت مورد اهمیت است. در این روش یک کیت مداری به شبکه متصل می‌شود. در صورت رخداد خطا در شبکه با عبور جریان از کیت‌های متصل‌شده و اندازه‌گیری امواج سیار مشتق جریان خطا و اعمال آن به یک فیلتر ریخت‌شناسی ریاضی، تشخیص خطا صورت می‌گیرد. تعیین محل خطا با استفاده از معادلات مداری و محاسبات جریانی صورت می‌گیرد. خطاهای اتصال قطب مثبت به زمین (PG)، اتصال قطب منفی به زمین (NG) و اتصال قطب مثبت به منفی (PN) به‌عنوان اغتشاشات خط DC در نظر گرفته شد. در تعیین نوع خطا از خروجی فیلتر ریخت‌شناسی ریاضی و تحلیل انرژی سیگنال استفاده شده است. روش ارائه‌شده در یک ریزشبکه MTDC متصل به منابع ذخیره‌کننده و تجدیدپذیر انرژی با خطاهای بسیاری آزموده شد. نتایج، بیان‌کنندۀ صحت روش پیشنهادی است. این روش نسبت به نویز با نسبت سیگنال به نویز بین 10 تا 70 درصد و تغییرات فرکانس نمونه‌برداری از 5/0 تا 50 کیلوهرتز و مقاومت خطا تا 100 اهم به‌صورت مقاوم عمل می‌کند و درصد خطای روش پیشنهادی کمتر از 3 می‌باشد. در خطاهای با امپدانس بالا تا 1000 اهم عملکرد بسیار خوب بوده و در بدترین شرایط خطا کمتر از 7 درصد است.
