A microgrid [1] is a decentralized group of electricity sources and loads that normally operates connected to and synchronous with the traditional wide area synchronous grid macrogrid , but can also disconnect to "island mode" and function autonomously as physical or economic conditions dictate. In this case the microgrid is also called an autonomous, stand-alone or isolated microgrid. In this way, microgrids improve the security of supply within the microgrid cell, and can supply emergency power, changing between island and connected modes.

The Features of the Smart MicroGrid as the Object of Information Modeling

For decades, most countries rely on large grids to fulfil electricity needs. However, with the rapid development of technology, there is a significant contribution from smaller grids all over the world in recent years, especially to fulfil the demands in remote areas.

Smaller grids comprise of mini-grids, microgrids and nanogrids. Mini-grids are the utility grid that is small in capacity and geography [1] or could be a group of some microgrids. The microgrid system is a small power supply system that consists of loads and distributed energy resources DER , such as renewable energy RE sources, co-generation, combined heat and power CHP generation, fuel cell and energy storage systems.

The Internet era has also brought the new development in the power sector as now we are starting to develop smart grids. It is the newest type of grids, involving smart technology. In comparison to microgrids, smart grids have digital information and control, dynamic optimisation of grid operation and resources, distributed resources similar with microgrids or specifically smart microgrids , demand responses, demand-side resources, energy efficiency EE resources, smart metering system, smart integration real-time response and timely information on consumption and advanced electricity storage.

Moreover, smart grids have other advantages such as faster protection, controlled self-heals, more robust, more renewable, more efficient, higher power quality, more reconfigurable and higher capacity factor. Of note, there is no fixed common definition on smart grids in this current stage of development, as each country may have its own definition. References 1. Nordman, B. Local Grid Definitions.

In this paper, we examine the significant role that buildings play in energy use and its management in a smart microgrid.

This paper describes the features of Smart MicroGrid and explains the of prior building appropriate information model of this system. It was determined information power system evaluation techniques and existing methods that can be applied in information system with simulation tools classification. This paper compares different tools for modeling, which are based on using renewable energy sources.

Smart grids — as a concept — became known over a decade ago and are essential in the digital transformation of the electricity sector. An introduction with definitions, trends and essential characteristics of smart grids. Big data analytics and IoT technologies are important technology drivers in smart grids whereby analytics shift to the edge, as in edge computing. A smart grid is an electricity network enabling a two-way flow of electricity and data with digital communications technology enabling to detect, react and pro-act to changes in usage and multiple issues. Smart grids have self-healing capabilities and enable electricity customers to become active participants.

However, a related concept, the microgrid, is something that owners and property managers should become familiar with. So what do these terms actually mean? To continue reading, click here.

Они вступили в опасную зону: Хейл может быть где угодно. Вдали, за корпусом ТРАНСТЕКСТА, находилась их цель - Третий узел. Сьюзан молила Бога, чтобы Хейл по-прежнему был там, на полу, катаясь от боли, как побитая собака. Других слов для него у нее не. Стратмор оторвался от перил и переложил пистолет в правую руку.

 Разумеется, не единственный. Но сегодня в шесть часов утра события стали разворачиваться стремительно. Дэвид говорит по-испански, он умен, ему можно доверять, к тому же я подумал, что оказываю ему услугу. - Услугу? - бурно отреагировала Сьюзан.  - Послать его в Испанию значит оказать услугу. - Да.

 Если Стратмор не забил тревогу, то зачем тревожиться. - Да в шифровалке темно как в аду, черт тебя дери. - Может быть, Стратмор решил посмотреть на звезды. - Джабба, мне не до шуток. - Ну хорошо, - сказал он, приподнимаясь на локтях.  - Может быть, у них закоротило генератор.

Пульс ее участился. На мониторе появилось символическое изображение конверта - это значило, что пришло сообщение по электронной почте. Сьюзан бросила быстрый взгляд на Хейла, но тот был всецело поглощен своим компьютером. Затаив дыхание, Сьюзан дважды щелкнула по конверту.

Я беру на себя верхнюю четверть пунктов, вы, Сьюзан, среднюю. Остальные - все, что внизу. Мы ищем различие, выражаемое простым числом.

Сдвоенная труба глушителя выбросила очередное густое облако, перед тем как водитель включил вторую передачу. Беккер увеличил скорость.
