Design and Control of Smart Loads using Improved Adaptive based P-Q Control

Smart grid technology offers to monitor grid generation for scheduling the load demands. Smart load is a technique for demand side management to optimize generation of grid. This paper focuses on control of an electric spring (ES2) based smart loads using adaptive technique. An adaptive control is used for extracting the fundamental component of load current with an adaptive noise cancellation (ANC) filter. A phase locked loop (PLL) is used to synchronize operation of ES-2 based on adaptive transfer delay ATD-PLL. An instantaneous reference active and reactive power of critical loads are estimated to control the ES-2. A full bridge voltage source converter (VSC) with battery at its DC link is used as an ES-2. Proposed concept of smart loads are modeled and its performance is observed under various dynamic situations.
