Estimating the Costs of Operating Reserve Provision by Poundage Hydroelectric Power Plants

The transmission system operators are entrusted with the task of ensuring stable and reliable functioning of the power system. In a modern power system, there are three groups of market actors who can be called upon by TSOs to aid in power system operation management: controllable generation, energy storage and controllable load. The owners of these assets can rightfully expect remuneration for their services from the TSO to recoup investment costs and operational expenses. This study is focused on poundage hydroelectric power plants and it strives to estimate the cost of operating reserve provision. Data of the large hydroelectric power plants located on the River Daugava is used for the calculation of costs and validation of the proposed algorithms.
