Energy Management System Design with Dispersed Storage and Generation

To be utilized with maximum effectiveness, the new forms of generation based on renewable resources iLtust be managed as part of existing power systems. Howevert many of these generators are by their very nature dispersed or small, so that they will be connected to the distribution part of the power system. This poses new questions of control and protection, and the intermittent nature of some of the energy sources poses problems of scheduling and dispatch. This paper assumes that the general objectives of energy management will remain unchanged, and discusses the impact of dispersed storage and generation on some of the specific functions of power system control, and its hardware.
