Step By Step Numerical Approach to a Self-Sufficient Micro Energy System Design

摘要

This paper presents a numerical approach to self-sufficient energy-system design. The main focus is to describe the methodology of designing an approach in several steps to find an optimally structured micro-energy system in accordance with the introduced decision parameters. A specific system model is presented that consists of an energy consumer, renewable and non-renewable energy-production facilities, energy-storage capacities and a control unit. Different operating conditions were identified for the system and various system configurations were simulated. Based on the input data and the decision parameters an optimal system was chosen that is able to provide a stable and optimal energy supply. The optimal configuration was found using the WSM method. The result is a specific structure of the energy system that meets all the requirements and boundary conditions of the presented numerical approach. Finally, the operation of the system is presented via timeline charts.
