Microgrid and Energy Management
Open. Modular. Secure.
Microgrids are autonomous, intelligent power grids with the capability to operate independently of the public network. A microgrid essentially acts as a decentralized energy system that both connects to and disconnects from the main grid.
A microgrid consists of energy consumers, energy producers, and often energy storage units. Smart components are used to ensure energy balance and voltage stability. Microgrids are not limited by size – any self-sufficient power system can function as a microgrid.
A microgrid offers multiple benefits, such as energy security in the event of power failure, as well as full, local control of the entire system.
Modern microgrids are usually powered by renewable energy sources such as wind, photovoltaic, hydro or CHP units, making them a sustainable and cost-efficient alternative to energy from the public grid, particularly when combined with energy storage facilities.
Microgrids usually rely on intelligent technological components, such as smart meters, which simultaneously turn them into self-sufficient smart grids. With this technology, energy from volatile power sources, such as wind turbines, can be easily and cost-effectively integrated into the power grid.

Solutions for Energy Supply – Energy management
The widespread use of electricity in all aspects of work and life offers a multitude of benefits, greater convenience and an improved quality of life. In order to ensure energy-optimized solutions in production, buildings and in infrastructures, there is a growing need for these to be based on suitable measuring systems. At the same time, the maintenance of supply security requires integrated solutions for operating grids and the standards compliant management of generating units. Bachmann offers both synergies through the direct integration in the PLC world as well as certified compliance with the latest regulations.

Smart Power Plant Controller (SPPC)
Our clever all-in-one solution.
PGS controller, compliant with connection guideline VDE-AR-N 4110 for supply
To operate a power plant (PGS) efficiently, the power management at the point of common coupling (PCC) is very important. The power plant could consist of different generation units (PGU), which are represented by combined heat and power units (CHP), photovoltaics (PV), wind turbines or storage components. A given power value could be set either manually or from a third party, e.g. direct energy trading. The resulting set-point for the different generation units in the park is calculated by the controller and then supplied to the units. According to the new requirements, which are valid from May 2019, it is mandatory for every power plant producing a power input >= 135 kW, to have a certified power plant controller, which has implemented the functionalities and follows the required rules.
Bachmann electronic provides an PGS controller, based on the proven Bachmann CPU´s and the extremely high accurate grid and measurement module (GMP232/x). In addition to this, it completely fulfills the connection guideline VDE-AR-N 4110 for power supply. The core component is the closed-loop-controller, which is a software module created by Bachmann with the extension M-Target for MATLAB®/Simulink®. This software module measures the values at the point of common coupling and with using the actual values from the park grid, it calculates the set-points and sends them to the different types of generation units.
All the required functionalities regarding set-points for active and reactive power, also the supply of these set-points towards the generation units, e.g. CHP, are implemented. To complete this product, a local HMI is also provided. It could be used for configuration, monitoring and operation.
This product is also shipped with a simulation library of the PGS controller for PC. This could be easily integrated into common grid simulator programs, which are normally used to certify the whole energy plant. To allow the access of direct energy trading (DET) or feed-in management signals (EINSMan), Bachmann has the most common communication protocols already included, e.g. IEC 60870-5-101/104, IEC 61850 or Modbus. These are easily to configure and beyond this, digital or analog signals could of course be used. In addition, this PGS controller solution provides the highest standards according to security, which checks and logs each and every access and change of value.
Application Development in all Languages – IEC 61131-3, C/C++ or MATLAB®/Simulink®
Programming is an essential part of the engineering process. Any possibilities to save time in this development step in particular are therefore desirable. The combination of optimum technology for the particular task and helpful functions increases efficiency and improves code quality.
Model-based development with graphical simulation and programming environments are becoming increasingly established tools for complex tasks. These reduce complexity and ensure that the focus is on what is essential: optimum task implementation.
Equipped for the future
The SolutionCenter and the Bachmann controller support a wide range of programming languages: C/C++, all IEC 61131-3 languages and MATLAB®/Simulink®. Programmers thus have the possibility to create applications in their familiar environment and language. Existing and established software code can also be reused without any problem. Libraries for PLCs can be created in all languages. The supported languages can also be combined as required.
World of Visualization – One software for all applications
M1 webMI pro
Native web technology used: M1 webMI pro makes it possible to use the advantages of web technologies entirely without restrictive add-ons such as browser plug-ins. All visualization devices from smartphones to powerful operator terminals can be connected, operated and monitored via a web server integrated directly on the Bachmann controller. Wherever and whenever the process requires it.
atvise® hmi
With the atvise® builder as an engineering tool with full graphic support, atvise® hmi offers everything needed for the rapid implementation of visualisations. In addition to an extensive object catalogue, drag & drop support and consistent object orientation, atvise® hmi users also have a fully integrated responsive design framework at their disposal. Numerous prepared dynamizations, drag-&-drop support and high degrees of freedom in implementation enable both beginners and experts to use the atvise® hmi optimally.
atvise® scada
Bachmann’s SCADA system offers a convenient and comprehensive system solution for web-based visualization projects. Maximum flexibility and openness ensure rapid implementation, good maintainability and the possibility to expand the installation efficiently. For example, the process values can be depicted fully according to the IEC 61400-25 interface. This not only simplifies internal communication but also provides external operators and energy companies with uniform access to the specific characteristic values.
Security Integrated in the Control system – Multi-level IT security concept
A selective security management system not only helps with unwanted and potentially destructive hacker attacks. Particularly in the protected environment of production plants, any accidental modification of machine parameters or configuration errors in the machine network are difficult to fully exclude. The effect of these, however, is often as serious as outside threats.
- Tap-proof data transmission through encrypted network connections
- Band width limitation to defend against overload attacks and for protection from faults in the network periphery
- Access control based on integrated user and password management
- Server and client authentication for the protection of automated teleservice accesses
- Secure end-to-end encryption to the latest state of the art (TLS 1.2)
- Rights are examined irrespective of the access path to the controller (visualization, SolutionCenter or with OPC UA)
- Restriction of system and execution rights for every user
- Role-based access control with groups (users inherit group rights)
- Configuration of access protection and visibility of files and process variables
- The saving and running of additional applications can be prohibited
- Memory protection measures so that third-party processes cannot access the memory of the application
- Detailed logging of all user accesses with all user data and partition encryption
- Open interfaces to adapt and enhance all access control functions and for the use of cryptographic functions in applications
- Backup and recovery mechanisms
- Predefined security levels as templates for simple configuration
Security as standard: Bachmann protects plants from production failure caused by unauthorized manipulation with a 5-level security concept. The entire Bachmann CPU product range comes with all security functions as standard. This therefore provides the user with an optimized ready-to-use security package.
I am interested in the expert workshop
and how Bachmann can help with my energy project.
