Resumen : | The economic effects of forecasting inaccuracies in the automatic frequency restoration service is analyzed in the context of the operation of a closed-loop and daily-cycle pumped-storage hydropower plant. The uncertainties when scheduling the automatic frequency restoration service are composed by the residual demand curves of the day-ahead reserve market, the upward and downward energy prices due to the activation of the reserves, and the percentages of the upward and downward real-time use of the committed reserves. The plant participates in the day-ahead energy market as a price-taker and in the reserve market as a price-maker, in the context of the Iberian electricity system. In addition, the energy due to the real-time use of the committed reserves is also considered. Results show that the profit is significantly more sensitive to forecast inaccuracies of the day-ahead energy market prices than of the prices and real-time use of reserves from the automatic frequency restoration service. |
