STRAtEGy Project

The STRAtEGy Project combines the efforts of three partners in Munich: Stadtwerke München GmbH (Munich City Utilities), IBH SYSTEMS GmbH (Developer of EclipseSCADA) and fortiss GmbH. The STRAtEGy Project focuses on development of next integration level of renewable energy sources, smart consumers and storage units into a virtual power plant (VPP).

The increasing number of small scale renewable energy sources that shall be integrated into virtual power plants challenge current SCADA architectures, due to the large number of data points that need to be handled in a central control center. Optimized schedules for a large number of generation and consumption devices will increase the calculation complexity as well as the monitoring and control effort. The “flat” architecture will quickly reach its limits, if all components are optimized and controlled by only one systems. Therefore, STRAtEGy introduces new layers of hierarchy with clustering and autonomous capabilities. Clusters monitor and control a set of components fully autonomous. Only if boundary conditions are violated, an active interaction between different clusters is initiated to reach the overall control goal of the VPP.


The primary approach of STRAtEGy is the integration of real and simulated systems in a scalable CO-Simulation platform. Models and real hardware components allow to assemble a real VPP 2.0 that is able to communicate with real systems using standardized protocols, while simulating new architecture concepts and control schemes to test their applicability. The approach is used to test VPP functionality with different types of resources such as solar, wind, micro block heat and power plants, cold storage houses and others. It also allows to evaluate different combinations of cluster composition and autonomous functionality.

In STRAtEGY fortiss develops the scalable CO-Simulation platform, that can handle 100.000s components and allows the integration of the OpenSource SCADA system (EclipseSCADA). This allows the parallel simulation combined with communication with real components. Additionally fortiss will build up the demonstrator together with IBH Systems and Stadtwerke München.

To establish a flexible connection of real systems with EclipseSCADA the second goal of STRAtEGy is the development of modular C(ompanion)-Boxes, that enhance the functionality of state-of-the-art industrial remote control systems (e.g. SPS systems). C-Boxes allow to add flexible operation schedules and local available autonomous functionality. The solution is aimed to be a cost effective extension of common infrastructure. A more complex task of the C-Box will be the cluster functionality to carry out optimization tasks to schedule and control cluster components. This will allow to create hierarchical layers and use C-Boxes as extension of the VPP infrastructure.
