The importance of accurate transmission system model for cross-border exchange of balancing energy

This paper investigates the value of nodal information of power systems in real-time. It is a fact that real-time security assessment of the power system requires nodal scheduling information of generating units, however, the value of this information from a market aspect is seldom discussed. In other words, precise schedules help the system operator not only assess the system security, but also estimate potential balancing energy exchange with neighbouring countries. This can be translated to the potential of establishing a real-time cross-boarder balancing market. This paper proposes an optimization-based method for cross-border balancing energy exchange and presents the results from applying the proposed method to the Swiss transmission system.
