As the penetration of wind energy increases in the utility grid, the intermittent nature of wind invariably imposes stress to the utility and creates chaos in scheduling energy dispatch. This situation can be improved to a greater extent by introducing energy storage systems along with the wind generation. The addition of energy storage ensures levelised energy output, supports the grid under fault,...
Rapid growth in wind generation is accompanied with increasingly large wind turbine sizes. While the large rotor size of utility-scale wind turbines can deliver greater economic benefits, the challenges associated with control system development can get significantly amplified with increases in turbine rotor spans. The aim of this paper is to identify and quantify the trade-offs involved with controlling...
This paper proposes a multi-objective optimization formulation to design a hybrid wind-photovoltaic-storage system to supply the demand. This design problem aims to minimize the annual cost of the overall system as well as the CO2 emissions, and is solved by Artificial Bee Colony (ABC) algorithm. Solar irradiation, wind speed, and load data are assumed deterministic. Prices are all empirical and components...
Analysis of wind speed fluctuation characteristics is very important for the study of the dynamic process of power system with wind power and the long-term economic scheduling of wind farm. This study aims to establish a wind speed model which reflects the wind speed fluctuation characteristics. The stochastic partial differential equation is applied to simulate wind speed and its variation. Using...
In this work, pitch controlled power regulation of a horizontal axis wind turbine coupled with a fixed speed asynchronous generator is studied using SimulationX®. Wind turbines need to be operated as per specified power output vs wind speed characteristics of it. If the wind speed is between the cut-in wind speed and the rated wind speed, then the wind turbine needs to be operated constant Cp. If...
