Abstract:

Power flow controlling Multi-Agent-Systems are potentially cost-effective short- and mid-term solutions for congestion management. Financial and operational advantages of such a system can be enhanced by the use of impedance controllers. To ensure reliable operation of these devices, an agent must be able to appropriately approximate an impedance controller's impact on line power flows. This can be achieved by calculating DC-sensitivities of the lines to small impedance changes with DC distribution factors. Conventional DC distribution factors are not applicable for this problem because of their non-linear behavior towards impedance changes. This is why a novel method for the calculation of DC-sensitivities for small impedance changes is proposed in this paper. The method only needs the grid's suscepetance matrix and the current power flow on the line equipped with the impedance controllers as inputs. The calculation is computationally inexpensive and delivers sufficiently accurate results. The sensitivities' linear behavior towards impedance change makes them easy to use for agents.
