Regional Analysis of Potentials of Flexibility Options in the Electricity System for the Study Regions Prignitz in Brandenburg and Anhalt-Bitterfeld-Wittenberg in Saxony-Anhalt

Abstract

The electricity system is changing. Due to the climate targets, the share of fluctuating renewable energy will continue to rise in the next few years, and conventional, fossil fuels will increasingly take a back seat. This creates the challenge of balancing supply and demand in the power system and increases the need for flexibility in the electricity system. In this article flexibility in energy systems is introduced, flexibility options are categorised along existing literature and a method is explained to approach the estimation of flexibility potential by means of two example regions. Therefore, 13 flexibility options in the electricity system in four categories are analysed: flexible generators, demand side management, storage, and power-to-X. By means of the two study regions Prignitz in Brandenburg and Anhalt-Bitterfeld-Wittenberg in Saxony-Anhalt, a practicable, transferable method to quantify and compare the technical potentials of the flexibility options at a high regional level is developed.

Estimation of the volume of production of turbine vapor of a fuel boiler with stochastic exogenous factors

“…Conceptual principles, methodology and practice of modelling water-steam processes of a fuel boiler of power plants [2][3][4][5][6][7][8][9][10][11][12][13], algorithms and object-oriented program codes for data processing of problems of system dynamics, white and pink noise [1,15], as well as models of difference-scheme equations [14, also see (1) and BoilerB in Fig. 1] and methods of numerical integration, such as Euler and Runge-Kutta methods.…”

“…We conduct a review of the literature on the following studies, for example, the article [2] considers the problem of balancing supply and demand in the Saxony-Anhalt's energy system and issues of ensuring flexibility in energy systems are studied in four categories: flexible generators, demand management, storage, and transmission of electricity at X, and developed a practical method for quantifying and comparing the technical capabilities of flexibility options at the regional level.…”

Smart Grid Technologies as a Concept of Innovative Energy Development: Initial Proposals for the Development of Ukraine

“…An alternative way out of this situation is the large-scale introduction of RES. An example of such an approach is Germany, according to an analysis by the Fraunhofer Society for Solar Energy Systems, the share of renewable energy sources (RES) in the structure of electricity production in Germany in 2019 was 46%, and on some days it exceeded 65% [16,17]. Reducing the use of coal has helped protect the climate.…”
