Dynamic Reactive Power Compensation of Large-Scale Wind Integrated Power System

Abstract: Due to progressive displacement of conventional power plants by wind turbines, dynamic security of large-scale wind integrated power systems is significantly compromised. In this paper we first highlight the importance of dynamic reactive power support/voltage security in large-scale wind integrated power systems with least presence of conventional power plants. Then we propose a mixed integer dynamic optimization based method for optimal dynamic reactive power allocation in large-scale wind integrated power systems. One of the important aspect of the proposed methodology is that unlike static optimal power flow based approaches, the proposed method considers detailed system dynamics and wind turbine grid code compliance while optimizing the allocation of dynamic reactive power sources. We also advocate that in large-scale wind integrated power systems, 1) better utilization of existing wind turbines especially wind farms with additional grid support functionalities like dynamic support (e.g., dynamic reactive power support, etc.) and 2) refurbishment of existing conventional central power plants to synchronous condensers could be one of the efficient, reliable and cost-effective option to address not only the issue of dynamic voltage security but also to strengthen other dynamic capabilities of the system including system inertia, etc. that are also significant challenges in large-scale wind penetrated power system. The proposed methodology is applied to the detailed model of the western Danish power system which is characterized by large-scale wind integration and least presence of central power plants.

Simulation of wind speed forecast errors for operation planning of multiarea power systems

Abstract: The amount of wind power has increased significantly over the last years. When the share of wind power increases it is necessary to consider the produced power in the daily operation planning of the power system. The first step is then to use forecasts of wind power. But the forecasts of wind power are in reality rather uncertain, so reserves have to be kept for unforecasted wind speed changes. But still an economical good solution is of large interest, and the consequence of this is to use stochastic optimization. To be able to do this it is necessary to have a view, so called scenarios, of possible outcomes of wind power. The aim of this paper is to provide a method that can simulate possible outcomes of wind speeds based on available forecasts. The method is based on the assumption that wind speed forecasts are available in several regions and the forecast errors in different regions are correlated. The developed method is based on multidimensional ARMA series.

Wind Power Curtailment and Energy Storage in Transmission Congestion Management Considering Power Plants Ramp Rates

Abstract: The integration of intermittent generation in power grids, such as wind energy, imposes new challenges for transmission congestion management In order to solve this problem, energy storage systems (ESS) have been proposed in the literature, as they provide an efficient mechanism for balancing variability while reducing operational costs This paper presents a comprehensive analysis of the dynamic interactions between wind energy curtailment and an energy storage system (ESS) when the ramping rates of power plants are considered An analytical framework is developed to study different mitigation measures in terms of total energy curtailed, total congestion costs, line load factor and congestion probability This framework is tested in a real case study and a sensitivity analysis is performed to identify the influence of the main ESS design parameters in congestion mitigation performance
