“…Centre of inertia based transient stability and frequency stability indices are developed to investigate the distribution of inertia following a disturbance in [4]. Additionally, the impacts of DSM on transient and small disturbance stabilities have been investigated simultaneously in [5] and it has been found that the same DSM action could improve small disturbance stability and deteriorate transient stability at the same time. There is clearly a need to develop an efficient way to evaluate overall system stability performance covering multiple stability aspects and balance sometimes different or even opposite impacts on different stability aspects.…”

With the ever-growing requirement of system stability enhancement, a comprehensive evaluation of overall system stability is coming into research focus to better understand and implement system stability enhancement solutions. This paper proposes a novel Composite Stability Index (CSI) for unified assessment of system frequency and angular stability and illustrates its application considering transient stability, small disturbance stability and frequency stability simultaneously, to assess the impacts of different load models and Demand Side Management (DSM) scenarios on either overall or individual aspects of system stability performance. The results show that the proposed CSI could clearly indicate the distance of operation points to the stability boundary, balance different and even opposite impacts on different stability aspects and quantify the impacts of different load models and DSM deployments on overall system stability performance. The results are illustrated on an equivalent model of four realistic interconnected transmission networks in a DigSilent/PowerFactory simulation environment.

Variable Renewable Energy Resources (VRES), especially wind and solar power, are known for their intermittent, uncertain, and low-energy-density nature. The increasing adoption of these stochastic sources presents irregularity in the net load in the power system network; therefore, it poses a challenge to the reliable operation of power systems. Consequently, there's an increasing need for power system flexibility to cope with VRES-related challenges. Flexibility planning will therefore be a crucial aspect for power system management, particularly as the penetration of VRES continues to rise. To reach this objective, the diversification of flexibility options emerges as a promising solution. Various strategies are prominent in the literature for enhancing power system flexibility to adapt to VRES variability. These include the utilization of flexible generators, adjusting load profiles through demand-side management, integrating energy storage systems and electric vehicle batteries, developing grid infrastructure, using surplus energy for various daily applications (e.g., heating), and the implementing of curtailment practices. Demand-side management and energy storage, for example, offer valuable flexibility by allowing consumers to adjust their consumption patterns to electricity supply and demand fluctuations. Additionally, flexible generation technologies like gas turbines and combined heat and power systems provide rapid responses, aiding grid balance during high VRES output variability periods. Overall, this paper provides an overview of power system flexibility, exploring the various flexibility resources available to VRES-related challenges. Finally, this paper emphasizes the importance of continued innovation in developing new flexibility solutions to meet the growing demand for sustainable and reliable power systems.
