چکیده مقاله :
يکي از موضوعات جديد در شبکه‌هاي قدرت مدرن، امکان تبادل اقتصادي انرژي بين بازارهاي برق موجود در کشورها يا نواحي مختلف است. اين موضوع خصوصاً در کشورهاي اروپايي تحت عنوان کوپلينگ بازارهاي برق مطرح شده است. در این مقاله، چارچوبی برای مدیریت تراکم شبکه انتقال و تسویه بازارهای برق چندگانه که در آن شرکت‌کنندگان امکان پیشنهاددهی به صورت هم‌زمان در بازارهای مختلف را از طریق خطوط بین‌ناحیه‌ای دارند، پیشنهاد شده است. در این چارچوب، بازارها به صورت مستقل چیدمان انرژی و ذخیره را انجام می‌دهند و یک نهاد هماهنگ‌کننده نیز تخصیص ظرفیت شبکه انتقال را بین آنها اجرا می‌کند. همچنين سه روش برای تسویه هم‌زمان انرژی و ذخیره پیشنهاد و امکان پیاده‌سازی آنها در شرایط بازارهای چندگانه بحث شده است. برای نشان‌دادن کارایی چارچوب پیشنهادی، آزمایش روی یک سیستم سه‌ناحیه‌ای 15شینه و سیستم استاندارد 96- IEEE RTS در شرایط سه‌بازاری انجام و مزیت آن نسبت به روش‌های دیگر تشریح شده است.
Energy exchange among the electricity markets is a new issue in modern power systems. This issue, especially in Europe, has been identified as a market coupling. In this paper, a framework for congestion management and clearing of multiple electricity markets, in which the market participants can place their bids simultaneously in different markets across an interconnection, is proposed. In this framework, the markets dispatch the energy and the reserve, independently. A central coordinator entity, then, runs the allocation of transmission capacity among the electricity markets. Three methods for simultaneous clearing of the energy and reserve are also proposed. The possibility of implementation of the proposed methods in multiple markets is discussed. The numerical results for three-area 15-bus and IEEE RTS-96 test systems in a triple-market case are presented, to demonstrate the effectiveness of the proposed approach as compared with the other approaches.
