“…The difference between energy allocated (reserved) and energy activated (used) for balancing is modelled with usage factor representing the ratio (0…100%) between energy allocated and energy activated. The determination of these usage factors is described in [6]. When RES generation units are prioritized in balancing markets the usage factor is equal to 1.…”

The total required ancillary services power will increase due to the decrease of the number of traditional generating units and rise of renewable energy resources (RES). New ancillary services providers will be necessary. Thus, RES could cover these new ancillary services needs. This study is focused on the PV system capability on 18 kV network to export ancillary services to transmission level. Three different commercial behaviours, product splits, with different power share in energy and balancing market are defined. In order to evaluate the proposed product splits their revenue is calculated. Past energy tariffs and market prices as well as ancillary services market prices are used. Based on past data on secondary and tertiary control powers, a scenario based on ancillary services market prices implementation is evaluated. Two options are considered: in option 1, the product split at maximum product price and product (secondary or tertiary control) is chosen for each time interval based on the mean price and standard deviation; In option 2, the product split at maximum product price and product is chosen for each instant based on prices. The revenues are calculated based on optimal power flow results for several proposed product splits and product options.

“…Revenues for energy generation are determined for both fixed published tariffs (current situation) and EPEX day-ahead prices (possible future option). Remuneration for voltage support by the DSO is estimated according to [6], i.e. according to the conformity of the DSO reactive power exchange with the transmission grid.…”
