SYSTEMS AND METHODS FOR CONTROLLING DISTRIBUTED POWER SYSTEMS USING DOWN-SAMPLING

Abstract:

A method for controlling a distributed power system is provided, the power system including an aggregator communicatively coupled to a plurality of nodes. The method includes receiving, at the aggregator, a specified aggregated power level, and at each of a plurality of sample times recurring at a regular interval, receiving, at the aggregator from each of the nodes, a condensed dataset, calculating, at the aggregator, a global value based on the specified aggregated power level, the condensed datasets, and a control prediction horizon, transmitting the global value to each of the nodes, solving, at each of the plurality of nodes, a local optimization problem based on the received global value and a local model prediction horizon for that node that is longer than the control prediction horizon, and controlling, at each of the plurality of nodes, a load based on the solved local optimization problem.
