Virtual plant as a part of smart grids

02.03.2011 | The past few years saw a massive increase in local energy sources (co-generation units, biogas stations, wind and solar plants) being connected to the transmission and distribution system. This phenomenon puts higher requirements on the management and control of the energy flow and the collection and processing of the related data. The current development in the area of managing the generation, transmission, distribution and power consumption in the existing system focuses on developing the so called ‘smart grids’ which are to enable the comprehensive management of the above-mentioned processes.

Smart grids provide the power producers and consumers with the opportunity to plan and monitor the power generation and consumption and therefore optimize the balance between the generation and consumption, so that potential risks are minimized (e.g. grid failure, energy losses, …). For consumers, smart grids mean reliable energy supplies and the option to manage your consumption depending on the suppliers peak tariffs and thus lowering your running costs.

If individual local sources and loads are aggregated in one whole system, it then can be monitored and managed centrally, this whole system is then called a virtual plant. A virtual plant consists of several management levels.

The management of individual power sources (such as co-generation or biogas stations) is the lowest level. Other modules of ‘smart’ management are the power generation optimization module (distribution of generation between individual units etc.), the load forecast or the weather forecast modules (monitors variable influences).

Our company has been working with the development and application of smart grids and in particular with virtual plants since 2007. We are experienced with deploying real projects in the application of central management of energy sources and facilities. These comprehensive solutions to central dispatching included the modules for managing individual energy sources, modules for communicating with the metering units, the SCADA system, the reporting and archiving systems, etc. At present, our Technology Development department is working on the development of the optimizers for the generation and load management.
