dc.description.abstract | Thermal power plants are forced to operate under frequent load changes in energy
systems with increased share of solar and wind power plants. These load changes
increase thermal power plant aging and reduce their efficiency. Therefore, solutions for
energy storage are sought in order to accumulate energy in periods of lower power
demand and produce excess power in periods of increased demands. In the present
paper the application of the steam accumulator is evaluated to provide the thermal
energy storage in the coal-fired thermal power plant and to increase its flexibility under
the demand for the variable load changes. The steam accumulator is charged during
periods of lower power demand, as during the night hours, and discharged during peak
load demands. The steam accumulator is charged by the steam extracted from the steam
turbine. The steam discharged from the steam accumulator increases the steam flow rate
through the turbine and the turbine power. Investigated are possible technical solutions
with the steam accumulator installations in the power plant. The upgrade of power plant
flexibility by steam accumulator is demonstrated. The corresponding operating
parameters and energy benefits are calculated. | sr |
