[ 1 ] - کنترل فرکانس‌بار در ریزشبکه جزیره‌ای با استفاده از کنترل پیش‌بین مدل
یکی از موضوعات مهم و اساسی ریزشبکه‌ها، در حالت جدا از شبکه قدرت، کنترل فرکانس و ولتاژ است. در این مقاله روشی مبتنی بر کنترل پیش‌بین مدل برای کنترل مقاوم فرکانس‌بار در یک ریزشبکه جزیره‌ای ارائه شده است. کنترل‌کنندۀ پیشنهادی در حلقه ثانویۀ کنترل فرکانس قرار دارد و با اعمال سیگنال کنترلی به منابع، اغتشاشات فرکانس به‌دنبال تغییرات توان در ریزشبکه کاهش می‌یابد. نتایج شبیه‌سازی انجام‌شده در محیط متلب...
[ 2 ] - Designing a Fractional Order PID Controller for a Two-Area Micro-Grid under Uncertainty of Parameters
Increasing the number of microgrids has raised the complexity and nonlinearity of the power system and conventional controllers do not present acceptable efficiency in a wide range of operation points. In this study, a fractional order proportional–integral–derivative controller optimized with hybrid grey wolf-pattern search algorithm is used to control the frequency of each area of the microgr...
[ 3 ] - Designing a new robust control for virtual inertia control in the microgrid with regard to virtual damping
Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...
[ 4 ] - A New Control Strategy for Controlling Isolated Microgrid
Microgrid control in isolated mode is a highly important subject area. In the present paper, a new method is used for controlling the isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, fuel cell). For the microgrid components with fast dynamics, a se...
[ 5 ] - Improving the stability of the power system based on static synchronous series compensation equipped with robust model predictive control
Low-frequency oscillations (LFO) imperil the stability of the power system and reduce the Capacity of transmission lines. In the power systems, FACTS devices and Power System stabilizers are used to improve the stability. Static synchronous series compensators is one of the most important FACTS devices. This paper investigates the damping of LFO with static synchronous series compensator (SSSC)...
