Fraunhofer Institute for Microelectronic Circuits and SystemsOptimized switching of flexible consumers, such as for charging electric cars, using decentralized, agent-based algorithms is the aim of the RESIGENT project. Dynamic tariffs from the electricity provider will provide incentives to a local energy management system. This coordinates the end devices in a property and avoids a blanket shutdown of grid users in an overloaded section. Read on to find out more about the goals, motivation and solutions of RESIGENT's partners.

RESIGENT - Intelligent energy management solutions for flexible consumers
Decentralized algorithms, dynamic tariffs, and resilience strategies for sustainable grid stability in the non-regulated electricity market
About the project
Motivation
The current developments in electromobility and the energy transition are already impacting the electricity market and grid directly. For example, there is a significant increase in grid loads with high simultaneity and long periods of use. On the other hand, there are the interests of electromobility customers and thus the energy market. The challenge of controlling the distribution grid currently offers only very limited opportunities on the market side to enable grid-friendly switching of consumers and generators or to create incentives for autonomously optimized grid behavior. It is therefore obvious that new system concepts, interfaces and market models are required.

It is therefore obvious that new system concepts, interfaces, and market models are required.
Solution
First, the exact arrangement of the components and their roles and functions are clarified. In particular, the functionality of a coordination function (KOF) to be created on the grid side is conceptualized and its interaction with the property at the grid connection point is defined. This includes communication via the »Smart Meter Gateway SMGW« to the »CLS - Controllable Local System«, the local energy management system. The KOF is to be placed in the backend of the active, external market participant (aEMT). Based on this structure, practical solutions will be developed. When implementing the CLS module, for example, two approaches are envisaged: firstly, implementation via an intelligent metering system infrastructure and an FNN-compliant (Forum Netztechnik/Netzbetrieb of VDE) control box using the IEC 61850 protocol, and secondly as additional logic on the EMS. In each case, the communicative connection to the EMS is to be implemented via EEBUS. The advantages and disadvantages of both options are to be investigated in the project.
Evaluation
The solutions developed will be tested and evaluated in selected grid sections in real scenarios in conjunction with a flexible electricity tariff. The results will be directly incorporated as a modular solution into the development of innovative products by the project partners involved. It is also planned that the results will be incorporated into the standardization process.
