Utilization of Battery Energy Storage Systems in the Červený Mlýn Plant to Extend Support Services to ČEPS
Zajac, Tomáš ; Sedlo, Aleš (referee) ; Radil, Lukáš (advisor)
The aim of master´s thesis is analysis of utilization of large-capacity battery energy storage systems, used in cooperation with facility Červený mlýn to supply ancillary services to ČEPS, a.s.. In the first part, categorisation of ancillary services is presented. Within the categorisation technical and legislative requirements on subjects providing individual services are defined, the overview of ancillary services providers is listed and the mechanisms of ancillary services procurement are elucidated. The thesis continues with an overview of accumulation technologies used in high-capacity application around the world and in Czech republic. Subsequently three technologies are presented – Li-Ion, NaS and VRB, which are considered as suitable technological solutions for given application. The last part of thesis deals with specification of parameters of the accumulation system, with selection of installation site within the facility and with description of operating modes while providing ancillary services. In order to evaluate the investment from an economic point of view, a model of sensitivity analysis is created and described and its outputs are presented and discussed at the end of the thesis.
