ملخص المقالة :
یکی از مهم‌ترین مشکلات موجود در شبکه‌های قدرت، وجود رزونانس در نقاطی از شبکه می‌باشد که باعث افزایش ناخواسته ولتاژ و جریان و بروز خسارت به تجهیزات مي‌شود. با توجه به این که با نصب بانک خازنی در شبکه، مشخصه فرکانسی سیستم تغییر کرده و امکان رزونانس افزایش می‌آید، لازم است این نکته در تخصیص خازن‌ها در شبکه در نظر گرفته شود. در اين مقاله، شاخص جدیدی برای ارزیابی وجود رزونانس ارائه شده و با استفاده از شاخص رزونانس پیشنهادی، روش جديدي براي جايابي بهینه خازن‌ها در محيط هارمونيکي ارائه مي‌شود. در روش پیشنهادی، ابتدا از آناليز حساسيت استفاده شده تا شینه‌هايي که بيشترين تأثير را بر تلفات و افت ولتاژ شبکه دارند، کانديد خازن‌گذاري شوند. پس از آن، خازن‌گذاري بر اساس سطوح بار مختلف و با استفاده از تابع شايستگي معرفي‌شده انجام مي‌شود. در تابع شايستگي، از توابع عضويت فازي مربوط به صرفه‌جويي اقتصادي، انحراف ولتاژ، THD و قيد رزونانس استفاده شده است. روش پيشنهادي با الگوريتم MSPSO، در شبکه 18شینه IEEE پياده‌سازي شده است. نتايج به دست آمده، کارامدي اين روش را در مقايسه با روش‌هاي ديگر نشان مي‌دهد.
