Smart Grid Distributed Synchronous Generation

Smart Grid (Smart Grid) is a fairly new term that has gained prominence since 2003. An example of the architecture of such a network is shown in the diagram below.

This definition of Smart Grid (hereinafter referred to as SG) combines several technologies in relation to power supply networks or, in other words, to a common power system (IPS). The smart grid has a number of advantages compared to the traditional IPS:

  • 1. SG is an automated network for the generation, transmission and consumption of electricity;
  • 2. SG is a S.M.A.R.T. system, that is, it is able to carry out self-monitoring and provide reports both on any network participants (its condition, needs, etc.) and complete information on the electricity produced and transmitted in any aspect: efficiency, losses or economic benefits;
  • 3. SG also improves the reliability of the network, providing imperceptible to the consumer switching to another source in the event of a failure of the main one. Since the reliability of individual power supply networks already reaches 99.97%, the use of SG is able to guarantee uninterrupted power supply 24/7;
  • 4. SG increases "performance" network as a whole by reducing losses in wires and optimal load distribution, establishing efficient (shorter length) connection routes for large consumers.
 

Data on the total consumption of the IPS of Russia for 2015

В России, зафиксированный максимум дневного планового потребления с начала 2015 года составил 2,44 млн. МВт*ч, причем суммарный объем планового потребления с начала года вырос на 1,1% по отношению к аналогичному периоду прошлого года и на 3.6% в Сибирском регионе.

Графиком нагрузки называют зависимость активной Р, реактивной Q или полной S мощности нагрузки от времени. Графики нагрузки могут быть суточными и годовыми.

Типовой суточный график нагрузки

В большинстве случаев в разные периоды года суточные графики нагрузки отличаются один относительно другого. Особенно значительно изменяется в средних и северных широтах осветительная нагрузка вследствие изменения продолжительности светового дня. При расчетах часто ограничиваются двумя характерными суточными графиками для зимнего (рис. 3.1, а) и летнего (рис. 3.1,6) дней. Годовой график (рис. 3.2, а) — это изменение по месяцам года максимальной получасовой нагрузки. Он характеризует колебания расчетной мощности объекта в течение года.

Для практических целей удобен годовой график нагрузки по продолжительности (рис. 3.2, б). На этом графике по оси абсцисс откладывают время (в году 8760 ч), а по оси ординат — минимальную нагрузку, которая соответствует этому времени. Годовой график по продолжительности составляют на основе суточных графиков за все дни года.

Высоковольтная линия (ЛЭП) Since energy consumption is constantly growing, the introduction of Smart Grid by upgrading existing networks represents a real alternative to the costly construction of generation facilities both large and local scales. Such systems are being implemented in the USA, Europe, Japan and China, since affordable energy resources are an extremely important component of a successful economy.

For any consumer, there are two options for obtaining capacity:

  • Variant A: Connection of capacities from the central power system. A common option in which power is purchased at the nearest low voltage substation in accordance with established tariffs
  • Variant B: Construction of a small generation facility. The disadvantages here are the uneven consumption of electricity and the lack of central support. In addition, any accident is a catastrophe and the termination of heat and power supply. Therefore, it is necessary to connect the power plant to the IPS, and these are additional costs (up to 2-3 times the cost of the power plant, depending on the distance to the high-voltage line). It is not possible to connect the power plant to a low voltage network, since these networks are passive and are not designed to receive electricity.

Innovative project UER — smart energy in Russia

Novosibirsk State Technical University together with CJSC «Tornado Modular Systems» developed the project "Smart Grid" - Smart Energy of Russia (SER), which allows to reduce the cost of connecting to networks by 5 times, due to the installation of special automation that takes over the functions power district management.

At present, the UER-Smart Grid product has passed prototype tests and is ready for implementation at any small generation facility.

Training simulators for physical micromodeling of automated power systems to train specialists in power system mode control have been created.

In general terms, the uniqueness of the proposed solution is based on patented technologies:

Automatic control of normal and emergency modes of electrical networks with distributed small generation

4-phase transmission of electrical energy over long distances

Decentralized multi-agent voltage regulation in distribution networks to ensure compromised power quality
