چکیده مقاله :
ریزشبکه‌ها در سیستم توزیع با بهره‌گیری از منابع انرژی پراکنده تجدیدپذیر قادر به تأمین بار خود در سیستم سطح ولتاژ پایین هستند و می‌توانند در قسمت‌هایی که دسترسی به شبکه برق سراسری امکان‌پذیر نیست با هزینه سرمایه‌گذاری کمتر استفاده شوند. ریزشبکه مورد استفاده در این پژوهش دارای منابع تجدیدپذیر بادی و خورشیدی و سیستم ذخیره‌ساز هیدروژنی می‌باشد. این مقاله، استراتژی مدیریت انرژی جدید را در ریزشبکه با وجود سیستم ذخیره‌ساز هیدروژنی و با در نظر گرفتن عدم قطعیت‌های منابع تجدیدپذیر ارائه داده است. مینیمم‌کردن هزینه بهره‌برداری باتری، سیستم ذخیره‌ساز هیدروژنی، هزینه مربوط به انرژی تأمین‌نشده و مازاد انرژی با در نظر گرفتن قیود تأمین بار از اهداف این استراتژی جدید می‌باشد. محدودیت‌های فنی در نظر گرفته شده در این مقاله شامل محدودیت‌های منابع تولید پراکنده و سیستم‌های ذخیره‌ساز هیدروژنی و باتری می‌باشد. سیستم ذخیره‌ساز هیدروژنی شامل الکترولایزر، تانک‌های هیدروژنی و پیل سوختی می‌باشد. برنامه پاسخگویی طرف بار به منظور مسطح‌کردن نمودار بار و بهره‌برداری بهینه از ریزشبکه به کار گرفته شده است. با استفاده از نرم‌افزار GAMS مدل پیشنهادی روی یک ریزشبکه اجرا شده که خروجی‌های حاصل از شبیه‌سازی این مدل روی ریزشبکه نشان می‌دهد استفاده از سیستم ذخیره‌ساز هیدروژنی و برنامه پاسخگویی بار باعث کاهش هزینه‌های بهره‌برداری ریزشبکه می‌شوند.
Microgrid (MG) supplied its local load with distributed energy resources at the low voltage system in distribution networks. Microgrid can be used in parts that are not allowed access to the electricity network with low investment cost. The used islanding MG in this research includes wind turbine and photovoltaic systems as renewable energy sources and hydrogen storage system (HSS). This paper proposes a new energy management strategy (EMS) for MG in the presence of the HSS considering the power uncertainties of renewable energy sources. The objective of proposed EMS is to minimize the operating costs of batteries, HSS and the costs associated with excess and undelivered energy considering the supplied load constraints. The considered technical constraints in this paper contain renewable energy sources limits and battery and HSS constraints. HSS includes electrolyzer (EL), hydrogen tanks and fuel cell (FC). Demand response program (DRP) is used to flat the load curve and optimal operation of MG. The proposed model on a MG is been implemented in GAMS software. The simulation results show that the operation cost of MG reduced by using of HSS and DRP.
