Prototyping Control Strategies for Prosumers: Insights into a Framework for Strategy Development and Analysis in Low Voltage Grids

Control strategies for prosumers in low voltage grids are gaining importance for ensuring the safe and reliable grid operation. These strategies have unique features and impacts on electrical grids, making selection challenging. This paper introduces a prototyping framework tailored to the development and analysis of control strategies, which focus on adapting power set points of prosumers within low voltage grids to tackle this problem. The framework encompasses conceptualization and simulations, in which the development and analysis of control strategies are covered. Thus, they are also prepared for further refinement in lab and field tests. Throughout this, aspects related to the effect of control strategies on electrical grids, including grid planning and operation, are covered. This paper presents the framework, covering general information on the development and analysis elements as well as details on the utilized modeling approaches and evaluation methods. Application examples of all framework elements illustrate their possibilities. For this, a practically relevant control strategy is selected, which has a positive impact on grid planning and grid operation by reducing the occurrence of critical grid situations. The strategy requires collaboration among system components, some regulatory updates, and data related to price curves and load behavior.
