Abstract
The integration of the renewable energy sources (RESs) into the power grid, drives a significant transformation in the conventional power generation landscape. This transition from traditional synchronous generators to inverter based RESs introduces unique challenges in maintaining the grid frequency stability due to the reduced system inertia. The inherent stochastic nature of the RES power generation, load demand, and grid inertia includes further complexity in the assessment of frequency stability. Existing studies have limitations, including neglecting the stochastic nature of RES generation and load demand fluctuations, relying on limited metrics, and lacking a comprehensive day-to-day assessment. To address these shortcomings of the existing approaches, this paper introduces a novel methodology for assessing frequency stability in power grids with high RES penetration. It proposes three indices for evaluating grid frequency sensitivity, resiliency, and permissibility amidst varying RES integration. Utilizing a stochastic approach, the study incorporates uncertainties in RES generation and load demand, offering a comprehensive framework for day-to-day frequency stability analysis. Additionally, it presents a systematic method to ascertain the necessary inertial support for maintaining desired frequency reliability in RES-dominated grids. The effectiveness of these methodologies is validated through a case study on a modified IEEE 39-bus test system, demonstrating their applicability in ensuring reliable grid operation under high RES scenarios.
This paper proposes novel indices and a methodology for evaluating grid frequency stability in the integration of renewable energy sources (RESs) into the power grid. It addresses challenges posed by reduced system inertia and stochastic nature of RES power generation. Using Monte Carlo simulation, the approach is validated on an IEEE 39-bus test system, demonstrating its effectiveness in assessing stability and determining needed inertial support for varying RES penetration levels. image
