Coordinated control of elements in Ubiquitous Power Networks to support Load Frequency Control

Within the carbon constrained world, virtually unrestricted integration of renewable energy sources into power networks is expected to become common in practice, making power systems to be more ubiquitous[1] in nature, structurally and operationally. Consequently, handling the intermittent and random behavior of renewable generation, thus Load Frequency Control (LFC), would become one of the major challenges in power systems operations in the future. In this paper we report a simple method that can support LFC of Ubiquitous Power Networks, rich in renewable generation. In the proposed method, frequency control support is achieved through the coordinated control of active power produced and consumed by various controllable system elements at distribution level where renewable generation is expected to appear in large scale. Simulation results obtained for a test system are also presented to demonstrate the effectiveness of proposed method.
