چکیده مقاله :
امروزه در صنعت برق طراحي و بهره‌برداري بهينه و مؤثر اقتصادي همواره مورد نظر بوده و در توسعه و بهره‌برداري از صنعت برق، هماهنگی شبکه برق و گاز به منظور حداقل‌كردن هزينه بهره‌برداري از اهداف اصلي به شمار مي‌آيند. در این تحقیق، بهره‌برداری غیر متمرکز شبکه‌های برق و گاز بر روی یک مطالعه واقعی در استان خراسان مدل‌سازی شده است. این مدل‌سازی از دیدگاه دو بهره‌بردار مستقل است که با در نظر گرفتن قیود فنی به دنبال حداقل‌کردن هزینه بهره‌برداری شبکه‌های برق و گاز می‌باشند. میزان مصرف گاز در شبکه‌های گاز و برق با استفاده از روش‌های مختلف ADMM، ATC و متمرکز مقایسه شده و در نهایت هزینه‌های بهره‌برداری در حالتی که یک بهره‌بردار مرکزی وظیفه بهره‌برداری از شبکه‌های برق و گاز را بر عهده دارد، در هر سه حالت مختلف با یکدیگر مقایسه شده‌اند. سناریوهای افزایش بار و سوخت دوم نیز مورد بررسی قرار گرفته‌اند.
Today, optimal operation and expansion planning have gained great attention in electricity industry optimizations and coordination of electricity and gas networks is one of the main goals in this procedure. In this study, decentralized operation of electricity and gas networks is modeled on a real-world case study in Khorasan province of Iran. This modeling is from the perspective of two independent operators who seek to minimize the operation cost of their subordinating network, considering technical constraints. In this way, the amount of gas consumption in gas and electricity networks is considered as a common variable and it is compared using different methods as ADMM, ATC and centralized. Moreover, operating cost is compared in all three different methods. Finally, scenarios of increased load and second fuel have also been investigated using the obtained model.
