چکیده

با گرم شدن شرایط آب‌و‌هوایی و رشد بار قابل توجه در بخش توزیع، مدیریت اوج سیستم قدرت در فصول گرما به یک مسئلۀ مهم تبدیل شده است و برنامه‏های پاسخ‌گویی بار یکی از مناسب‏ترین روش‏های متداول برای مدیریت اوج بار شبکه است. نویسندگان در این مقاله رویکرد نوینی را برای مدیریت اوج شبکه در شرایط بحرانی و توسط شرکت توزیع پیشنهاد می‏دهند. این رویکرد، برنامه‏ریزی بهینۀ منابع انرژی پراکنده و منابع متنوع پاسخ‌گویی بار در راستای کاهش اوج مصرف شبکه در ساعت‌های اوج بحرانی و با کمترین هزینه است. منابع پاسخ‌گویی بار در این مقاله شامل سه برنامه قیمت‌گذاری اوج بحرانی، کاهش بار تشویقی و پاسخ‌گویی بار اضطراری است که توسط شرکت توزیع اجرا می‏شود. بهینه‏سازی این مسئله به واسطۀ یک برنامه‏ریزی ریاضی مقاوم و با در نظر گرفتن عدم قطعیت تولید منابع تجدیدپذیر صورت می‏پذیرد. نتایج به‌دست‌آمده نشان می‏دهد ارائۀ قیمت اوج بحرانی مناسب نه تنها بر کاهش مصرف بارهای الاستیک، بلکه بر نحوۀ همکاری سایر مشترکین در برنامه‏های کاهش بار و اضطراری نیز تأثیر می‏گذارد. همچنین، برنامۀ پاسخ‌گویی بار اضطراری با در اختیار قرار دادن ظرفیت انرژی مناسب در ساعت‌های محدود، نقش مهمی در مدیریت بار اوج دارد. تأثیر بار پیش‌بینی‌شده از سوی شرکت توزیع برای بازۀ ساعتی مدیریت اوج مقداری مثبت و برای زمان‏های غیر اوج منفی می‏شود. ضمن اینکه باید توجه داشت ریسک‌گریزی اپراتور و دخالت دادن عدم قطعیت موجب افزایش تأثیر بار می‏شود.

چکیده [English]

With the warming of the weather conditions and significant load growth in the distribution sector, peak management in power systems has become an essential issue in hot seasons, and demand response programs are one of the most suitable common methods for managing peak. In this article, the authors propose a new approach to network peak management in critical conditions by the distribution company. This approach is the optimal scheduling of distributed energy sources and various demand response resources to reduce the network's peak consumption during critical peak hours and with the lowest cost. Demand response resources in this article include the three critical peak pricing, incentive-based load curtailment, and emergency load response, which the distribution company implements. The problem is optimized using a robust complex number linear programming and considering the power uncertainty of renewable resources. Providing a peak price 14% larger than the peak price of the normal tariff can bring a suitable load impact from the critical peak program customers in the network. The participation of customers in the load curtailment program in the beginning and end hours of peak management is equal to 30% and 20% of the customer's baseline. Considering the risk related to solar production, power contribution in this program increases by 117 and 74 kilowatts for the same hours. Adopting a risk-averse strategy increases the cost by 745 $ for the distribution company and the reason is the increase in curtailment of 120 kW through the emergency demand response program.
