Grid-Aware Demand Management in Electricity Distribution Grids

Research output: Research - peer-reviewJournal article

Abstract

Certain electricity prosumers in the low- and medium voltage grid can offer flexibility to the grid. Such flexibility can be exploited in demand management systems, e.g. by utilities and aggregators. Typical realization instrument is via economic incentives, for instance using variable energy prices. This paper presents an extended demand management approach that focuses on two aspects: (1) introduction of an interface to the Distribution System Operator in order to allow for grid load management (overload avoidance); (2) end-to-end robustness to changes of real-time information, in particular addressing variable communication network behavior as it may result from the use
of shared communication network infrastructure. The paper presents algorithms that realize such demand management on different levels in a hierarchical control system, defines and implements the related protocols for message exchanges, investigates the resulting performance and efficiency of the demand management solution in a hybrid testing environment and finally verifies the simulation results using a hardware-in-the-loop approach with actual
protocol realizations.
