Dynamic dimensioning of balancing reserve

Dimensioning and procurement of sufficient balancing reserves are elementary to safeguard operational security as well as frequency quality. Nevertheless, the current development and structural changes in the electrical power system lead to new challenging tasks in terms of balancing the system while using the interconnected system and resources in an efficient way. This as well as the increasing volatile feed-in of renewable energy sources rises the questions of the validity of static methods to dimension reserves. Therefore, this paper presents a method to determine the demand of balancing reserve with a dynamic approach — allowing to take the effects of the Imbalance Netting Process into account. Notwithstanding, a sufficient amount of balancing reserves in every situation has to be determined to ensure a secure network operation at all times.
