Abstract
In the context of the energy transition, energy system planning is becoming increasingly relevant for decentralized systems. Motivated by the strong increase of publications on municipal energy system planning (MESP), these studies are subjected to a bibliometric analysis in this paper. The 1235 articles, which are based on the Web of Science database, are examined using the R-tool bibliometrix. The study shows that China is the most important contributor with 225 articles, followed by the USA (205) and Germany (120). Most cross-country collaborations were conducted between China and Canada, focusing mainly on uncertainties in MESP. Among the institutions, the North China Electric Power University is responsible for most articles (42). The core journals on MESP are Energy, Applied Energy, Energy Policy, Energies and Renewable Energy, which published 37% of the 1235 articles. Publications on MESP focus on renewable energies, optimization and hybrid energy systems. Furthermore, district heating seems to be a core topic in MESP and is addressed in three of the top five most cited articles. The demonstration of global research trends in MESP can support researchers in identifying the relevant issues regarding this expanding and transforming research area.

In 2015, 197 countries agreed on the Paris Climate Convention, which includes limiting global warming to below 1.5 ◦ C and reducing greenhouse gas emissions [1]
municipal energy system planning (MESP) means that the municipalities are becoming involved in energy system planning: they increasingly own and operate decentralized renewable energy systems and their energy demands are less covered by centralized plants
Infer trends over time show themes researched identify shifts in the boundaries of the disciplines detect most prolific scholars, institutions and countries present an overview of the extant research. These objectives should be achieved with the present review study on MESP
Summary
In 2015, 197 countries agreed on the Paris Climate Convention, which includes limiting global warming to below 1.5 ◦ C and reducing greenhouse gas emissions [1]. To achieve this objective, a decarbonization of the energy system is necessary. The increase of the share of low-emission renewable energy in the energy mix could contribute to the decarbonization. MESP means that the municipalities are becoming involved in energy system planning: they increasingly own and operate decentralized renewable energy systems and their energy demands are less covered by centralized plants.
