Abstract

The most important and oldest challenge in power system analysis is to solve the load flow problem. Simple examples are presented here to illustrate the old idea of distributed Slack-bus. The load flow equations are shown to include distributed bus slack. The Newton-Raphson equations for load flow have been rewritten in a matrix format as well. Distributed slack bass is demonstrated with a 5-bus system. Reducing power system losses is its most important advantage.

Keywords: Load flow, Economic dispatch, Slack bus, Distributed Slack bus.

چکیده

حل پخش بار سیستم قدرت مهم‌ترین و قدیمی‌ترین چالش در تحلیل سیستم‌های قدرت به شمار می‌آید. در این مقاله ایده قدیمی اسلک باس توزیع شده با مثالهایی ساده ارائه شده است. نشان داده شده است چگونه باید اسلک باس توزیع شده را در معادلات پخش بار اضافه کرد. همچنین معادلات پخش بار نیوتن رافسون به صورت ماتریسی دوباره بازنویسی شده‌اند. با یک سیستم 5 باسه، مزایای اسلک باس توزیع شده نشان داده شده است. مهم‌ترین مزیت آن کاهش تلفات سیستم قدرت است.

کلمات کلیدی: پخش بار، پخش بار اقتصادی، اسلک باس، اسلک باس توزیع شده
