In this paper, a battery energy storage system (BESS) based control method is proposed to improve the damping ratio of a target oscillation mode to a desired level by charging or discharging the installed BESS using local measurements. The expected damping improvement by BESS is derived analytically for both a single-machineinfinite-bus system and a multi-machine system. This BESS-based approach is tested on a four-generator, twoarea power system. Effects of the power converter limit, response time delay, power system stabilizers and battery state-of-charge on the control performance are also investigated. Simulation results validate the effectiveness of the proposed approach.

“…For the analysis of local interactions with the power system, the converter can usually be simplified as a controllable voltage source, whilst retaining a detailed representation of the converter controllers [4], [5]. Moreover, a reduced model of the AC system, namely a voltage source with a complex impedance based on the short-circuit ratio (SCR) at the Point of Common Coupling (PCC), is in general sufficient to study the stability of the controller [6], [7].…”

Abstract-In this paper, a methodology is presented to identify and analyse interaction modes between converters in Voltage Source Converter Multi-Terminal High Voltage Direct Current (VSC MTDC) systems. The absence of a substantial level of energy stored in such power electronics based systems results in fast system dynamics, governed by electromagnetic phenomena. Moreover, interactions between components are largely influenced by the control parameters and in general, an a-priori identification of interaction modes based on associated time constants is less straight-forward than in AC systems. Furthermore, the extent to which converters interact not only depends on the controller parameters, but is also influenced by the physical characteristics of the HVDC system. The methodology introduced in this paper is based on aggregated participation factors to distinguish between local modes, primarily associated with one terminal, and interaction modes involving multiple terminals. To illustrate the proposed methodology, the influence of droop control parameters, as well as DC breaker inductors, on the system dynamics and the participation of the terminals are investigated for a three-terminal MTDC system.
