Modified stochastic algorithm for decentralized active demand response (DADR) system supporting primary load frequency control

The concept of decentralized demand response systems is not new, however descriptions of such systems are usually limited to general ideas and possible system services. In this paper the original modified stochastic Decentralized Active Demand Response (DADR) control algorithm has been presented. Fulfillment of the theoretically assumed properties has been numerically tested in a specially elaborated simulation arrangement based on a well-known model of the power system. Applicability of the proposed control algorithm has been initially tested using a specially developed prototype.
