Abstract
This paper presents an idea with the distributed energy storage to regulate grid frequency. During the operation of an automatic generation control (AGC), a fleet of aggregated electrical vehicle (EV) is considered in operating mode for LFC. Two area power systems in an isolated mode with the thermal-hydro and thermal–thermal non-reheat systems are considered for AGC operation. Under the restructured environment, the power exchange contracts between distribution companies (DISCOs) and generation companies (GENCOs) are represented by a contract matrix known as DISCO participation matrix (DPM). Dynamic study of frequency deviations in the power system by load fluctuation under poolco based as well as bilateral contracts with its violation conditions has been considered and simulated. Finally, an electric vehicle as a huge storage of distributed battery energy system has been proposed as a result of its quick response against load variation. Simulated analysis with DISCO participation has been considered throughout the work. The superiority of the grid-connected distributed energy storage (EVs) has been shown by comparative analysis with and without EVs to damp out frequency oscillations.
