In this paper we demonstrate the contribution of information systems towards a sustainable and reliable power supply. Following a Design Science approach we develop an information system for microgrid operation at a U.S. army base. Microgrids enable an improved integration of distributed renewable energy sources and increase the robustness of the overall power grid. The microgrid in this study ...

A MicroGrid without a central fast-acting controller or a central energy storage unit was considered in order to establish the problems of a MicroGrid using traditional technology and to identify the additional benefits which could be derived by installing supplementary hardware (i.e. energy storage and central control). In view of the fast expanding electric drive vehicle market, fuel cell car...

Renewable energy has attracted significant attention over the last decade, conceivably due to its environmental benefits and the recent drops in the development and deployment cost of the technology. The increase in renewable generation, however, has resulted in new challenges in supply-load balancing, owing to its intermittent, non-predictable and volatile generation features. Several methods ...

Recently, economic and environmental problems have created a strong attitude toward utilizing renewable energy sources (RESs). Nevertheless, uncertainty of wind and solar power leads to a more complicated energy management (EM) of RESs in microgrids. This paper models and solves the EM problem of microgrid from the generation point of view. To do this, mathematical formulation of a grid- connec...

A microgrid is an eco-friendly power system because renewable sources such as solar and wind power are used as the main power sources. For this reason, much research, development, and demonstration projects have recently taken place in many countries. Operation is one of the important research topics for microgrids. For efficient and economical microgrid operation, a human operator is required ...

Microgrids are increasingly being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. However, the technical challenges associated with the operation and controls are immense. Management of dynamic power balances, power flow, and network voltage profiles imposes unique challenges in the context of microgrids. Stability of t...

Alternative Energy is becoming a popular and an essential energy resource in the current century. This paper investigates the effect of using a hybrid microgrid system in Langkawi and Socotra Islands. Configuration of the optimal hybrid system is selected based on the best components and its sizing with appropriate operation strategy to provide a cheap efficient, reliable and cost effective sys...

When a microgrid is mainly supplied by renewable energy sources (RESs), the frequency deviations may deteriorate significantly the power quality delivered to the loads. This paper proposes a frequency-based control strategy, ensuring the frequency among the strict limits imposed by the Standard EN 50160. The frequency of the microgrid common AC bus is determined by the energy storage converter,...

Microgrids are an increasingly popular class of electrical systems that facilitate the integration of renewable distributed generation units. Their analysis and controller design requires the development of advanced (typically model-based) techniques naturally posing an interesting challenge to the control community. Although there are widely accepted reduced order models to describe the dynami...
