• Decentralized Active Demand Response system with the stochastic control algorithm.
• Original and application ready Decentralized Active Demand Response (DADR) system.
• Mathematical description of the proposed DADR control algorithm.
• Numerical simulations for various circumstances resulting from parameter selection.

The concepts of decentralized demand response systems are present in the state of the art literature, however, the material is limited to general ideas and possible system services. In this paper the original and application ready proposition of Decentralized Active Demand Response (DADR) system realization is presented in the form of a stochastic control algorithm. Such an approach to the system description enables simulation investigations of the DADR system as an element of dynamic stability improvement of an electrical energy distribution network. The results obtained from simulations have confirmed that the proposed DADR solution, because of its high dynamic response in dealing with disturbance phenomena, might be used as part of both primary and secondary Load Frequency Control in electrical power systems.
