Multi-factor modelling of electric grids for social and technical impact studies

Abstract

This paper proposes a load flow-based approach to analyze electric systems, with the aim of considering multiple factors in grid studies, including technical, social, environmental, and economic factors. The proposed method enables the graphical design of grids, and the seamless integration of models of distributed generation, residential loads, and economic signals, such as day-ahead prices. The validity of the approach is demonstrated by comparing its results against the traditional iterative load flow analysis approach. Several test cases are presented to showcase the model’s capabilities in studying economic and environmental factors. Notably, the study of residential loads generated for different scenarios enables the observation of the impact of social factors, such as household size, on the grid.
