Abstract
The paper presents technical solutions for a power grid that undergoes the elimination of a significant number of coal-based power generating units. The purpose of the solutions is to adapt the existing machines with sufficient lifespans to the new operating conditions. In particular these include steam turbines. The steam turbines’ cycles may be extended with energy storage systems based on a molten salt. This allows to increase the flexibility of the power generating units while maintaining the largest possible efficiency of the power generation. The solutions presented here allow to connect the steam turbines cycles to renewable energy sources and reduce the overall number of the units that create the fundamental layer of the power grid. The analysis of the solutions involves numerical modeling. The paper describes the assumptions and the results of the modeling for chosen cases of the modernization. The researched considered a number of options that differed in the investment costs and the resulting performance.
Highlights
According to the current policies in the power generation industry the energy systems should increase the share of the renewables in the generation of the electric power
For safety reasons power grids must be able to compensate for any drops in the power generated by the renewable energy sources
In the countries where power grids have relied on fossilfueled plants it is natural and economically justified due to the investment costs paid so far to maintain the foundation in the current form at least until the return of the investment costs is secured [1]
Summary
According to the current policies in the power generation industry the energy systems should increase the share of the renewables in the generation of the electric power. A transition from a coal-based system to a green energy one is a complex and a very challenging task It should be conducted with the upmost respect to the local operating conditions of the machines. The presence of the foundation is necessary due to the specific way the renewable energy sources operate, which depends strongly on the environmental conditions. This is especially important for wind and solar energy. In the countries where power grids have relied on fossilfueled plants it is natural and economically justified due to the investment costs paid so far to maintain the foundation in the current form at least until the return of the investment costs is secured [1]. The foundation means the power units with large power supercritical steam turbines
