Load kick-back effects due to activation of demand response in view of distribution grid operation.

摘要

There are increasing potentials to utilize the flexibilities from demand side resource (DSR) units. They can provide grid operation services by shifting or curtailing their energy consumption. The service provision can be achieved by aggregating a large quantity of DSR units in the network. The paper has shown how aggregated consumption dynamics introduce new peaks in the system due to the synchronous behaviors of a portfolio of homogeneous DSRs, which is instructed by the flexibility management system. This dynamic effect is recognized as load kick-back effect. The impact of load kick-back effects onto the distribution grid is analysed in this paper by establishing scenarios based on the estimation of DSR penetration levels from the system operator. The results indicate some risks that the activation of demand response may create critical peaks in the local grid due to kick-back effects.
