CV from Guido Pleßmann

Guido Pleßmann

Guido Pleßmann was born on the 8th of September, 1986 in Göttingen and passes his A-level at the „Freie Waldorfschule Göttingen" in 2006.

Motivated by his interest to relieve the electricity generation from dependence of fossil resources, he started studying renewable energies technologies at the university of applied sciences Nordhausen. After completing his bachelor studies he continued with the masters program „Umwelttechnik/ Regenerative Energien" at the university of applied sciences HTW Berlin. During this course of studies Guido Pleßmann was employed as tutor for three terms. He finished the course of studies with a master thesis titled „Development of a transmission grid model for a simulation framework of the electricity sector", which was conducted at the Reiner Lemoine Institute under supervision of Prof. Jochen Twele. During the work at the Reiner Lemoine Institute the idea was developed to continue the work on energy system modeling and analysis in the context of a doctoral thesis. From the end of the course of studies until the start of the scholarship of the Reiner Lemoine Stiftung he was employed at the Reiner Lemoine Institute as research assistant.

Short description of the doctoral thesis:

„Contribution of transmission grids to the global energy supply with renewable energy resources"

Due to growing scarcity of fossil resources, the negative impact of climate change and dwindling acceptance of nuclear power generation, a change in energy supply in the future is inevitable. Future energy supply will be predominantly based on wind energy, solar energy, hydro power and other renewable resources according to the local potential. Growing volatility on the supply side requires increased balancing capacities, which can be provided by gas power plants or storage units. Very high shares of renewable energy resources require increased use of balancing capacities provided by storages in order to supply balancing power based on renewable resources. Transmission grids enable balancing effects on the demand and the supply side and this can lead to a reduction of other necessary balancing capacities.
In the planned doctoral thesis interdependencies between decentralized storage demand and centralized grid infrastructure of future energy systems with very high shares of renewable energy resources will be analyzed, with focus on electrical energy systems. It will be analyzed to what extend the use of spatial and temporal balancing effects, introduced by transmission grids, reduce storage demand.
The investigations will be conducted by techno-economic analyses using a multi-region energy system model. The model bases on an optimization approach and represents all components of the energy system in an abstract way. The objective of the investigation is to quantify the impact of balancing effects of demand and supply, which are enabled by utilization of transmission grids. Furthermore, economical optima of decentralized and centralized energy supply will be analyzed considering their implementation time horizon. The results of this work should help to assess the role of transmission grids in terms of implementing the transformation of the energy system.
