Off-Grid Systems

In the research unit Off-Grid Systems, we develop electrification strategies based on renewable energy for developing regions. More precisely, we optimize hybrid mini-grids using simulation models and geo-information systems (GIS).

More than 1.3 billion people worldwide live without access to reliable and affordable electricity. One solution for electrification are decentralized energy systems that make use of local renewable resources. With our research, we want to contribute to the disclosure of the economic and ecological potential of renewable energy in developing regions. Many technologies are already cheaper today than conventional energy sources and additionally reduce local and global emissions.

Our interdisciplinary and international team works partly with in-house energy simulation models, partly with database analyses and GIS programs. In addition, we conduct field studies on social, demographic, and economic conditions in a region. In this way, we can assess the business environment in order to propose both ecologically and financially sustainable solutions for local power supply.

Tools

open_plan

The open_plan tool supports the optimized planning of energy cells to (partially) meet electricity and heating demands in neighborhoods and industrial areas in Germany.

CP Nigeria

The CP Nigeria tool helps representatives of unelectrified communities in Nigeria design mini-grid implementation plans.

RAMP

The software was co-developed by RLI scientists and helps with the stochastic simulation of energy user-controlled time series based on a few simple inputs

Offgridders

The simulation tool generates a model of a user-defined power supply system, optimizes the capacities of the generation, storage and electrical components of the system and then performs a deployment optimization of the optimized capacities.

Multi-Vector-Simulator

The tool enables the evaluation of local sector-coupled energy systems that include the energy sources electricity, heat and/or gas
