چکیده مقاله :
در این مقاله، از روش کنترل مدل پیشبین اقتصادی برای کنترل و بهره¬برداری بهینه از تعرفه سیستمهای فتوولتائیک، دیزل ژنراتور و ریز شبکه¬ها با دو شرایط جزیره¬ای و متصل به شبکه، استفاده شده است. به¬منظور داشتن عملکرد بهینه، از روش¬های کنترلی شامل سیستم کنترل حلقه بسته، کنترل بهینه حلقه باز و تقویت حلقهی باز اولیه استفاده شده است. هدف اصلی این مقاله به حداقل رساندن انرژی شبکهی برق و هزینه¬های سوخت از طریق ارزیابی محدودیت¬های مربوط به سطح تراز سوخت در مخازن سوخت دیزلی می¬باشد. در روش¬های کنترلی استفاده شده علاوه بر انطباق با محدودیت¬ها در بین متغیرهای قابلکنترل، الزامات بار نیز برآورده می¬شود. به ¬منظور به ¬دست آوردن مزایای بازخورد و پیش¬بینی، زمان¬بندی توان بهینه به عنوان یک مسئله کنترل سیستم انرژی پشتیبان و نیز دیزل ژنراتور متصل به ریزشبکه بر اساس ساختار برنامهریزی خطی مدلسازی شده است. به طور خاص، تجزیه و تحلیل به دو گروه تقسیم می¬شود. اولین مورد در مدل جایگزین زمانی است که خاموشی بین ساعت 7 صبح الی 6 بعدازظهر اتفاق میافتد و دیگری در حالتی است که کل شبکه در 24 ساعت در دسترس می¬باشد. بررسی وضعیت مصرف انرژی نشان میدهد، صرفه¬جویی در هزینه و بالا رفتن درآمد، با استفاده از روش پیشنهادی بهبود یافته است. به طوری¬ که، صرفه¬جویی در مصرف انرژی روزانه می¬تواند تا 52 درصد باشد. درحالیکه مصرف انرژی دیزل تا 85 درصد کاهش می¬یابد. کنترل عملیات بهینه می¬تواند بهخوبی با عدم قطعیت و اختلال درنتیجه استفاده از روشهای کنترلی ارائه شده، همراه باشد.
In this article, the control method of the economic predictive model for the use of the efficiency tariff of the photovoltaic backup system, diesel generator and microgrid, connected to the grid using the closed loop control system, the optimal open loop control, and also through the control and strengthening of the primary open loop has been The main goal of this study is to minimize the power grid energy and fuel costs by evaluating the limits related to the level of fuel level in diesel fuel tanks. In addition to complying with the restrictions among the controllable variables, this control method also meets the load requirements. In order to obtain the benefits of feedback and predict the optimal power timing as a back-up energy system control problem, as well as the diesel generator connected to the microgrid, it is modeled based on the linear programming structure. Specifically, analysis is divided into two groups. The first case in the alternative model is when: outage occurs between 7 AM and 6 PM and the other in the grid energy state occurs when the grid is available for more than 24 hours. Energy performance shows, cost savings and income, in the control of daily economic forecasting model has improved. As long as, daily energy saving is up to 52%, while diesel energy is up to 85%. Optimum operation control can be well associated with uncertainty and disturbance in the result.
