In a wind farm, the upstream wind turbine may cause power loss to the downstream wind turbines due to the wake effect. Meanwhile, the energy production is determined by the power generation and the lifetime of the wind turbine. In this paper, an optimal active power control method is proposed to maximize the energy production of wind farms by considering the wake effect and the lifetime of wind...

This paper presents the particle swarm optimization (PSO) for reactive power and voltage control (Volt/Var Control) in distribution system considering DFIG wind farm. In this paper, the reactive power output of DFIG wind farm has been considered as the control variables in the Volt/Var Control scheme by considering the reactive power compensation capability of DFIG. The minimization of total sy...

The present paper investigates how a storage unit, coupled with a wind farm could influence the economic operation of the power system. For this reason two optimization algorithms are implemented, where the storage capacity is assigned certain costs and is able to vary in size. The objective of the first optimization is to identify the optimal power infeed as well as the necessary battery capac...

In the coming years the geographical distribution of wind farms in Great Britain is expected to change significantly. Following the development of the “round 3” wind zones (circa 2025), most of the installed capacity will be located in large offshore wind farms. However, the impact of this change in wind-farm distribution on the characteristics of national wind generation is largely unknown. Th...

In this paper, particle swarm optimization is utilized to optimize the placement of wind turbines in a wind farm. Since wind is one of the sustainable energy sources, it is important to build the wind parks as efficient as possible to extract the largest possible amount of electrical power. Here, the location of each wind turbine is adjusted within a predefined square field considered as a wind...

Due to the intermittency of wind power generation, it is very hard to manage its system operation and planning. In order to incorporate higher wind power penetrations into power systems that maintain secure and economic power system operation, an accurate and efficient estimation of wind power outputs is needed. In this paper, we propose the stochastic prediction of wind generating resources us...

Abstract: In modern wind farms, maximum power point tracking (MPPT) is widely implemented. Using the MPPT method, each individual wind turbine is controlled by its pitch angle and tip speed ratio to generate the maximum active power. In a wind farm, the upstream wind turbine may cause power loss to its downstream wind turbines due to the wake effect. According to the wake model, downstream powe...

Applying 4-levels grid nested WRF (Weather Research and Forecasting) model to predict meteorological elements of wind farm field, and employing WRF model outputs and SCADA data of wind turbines to construct wind power forecast models by using the APLSR (Adapting Partial Least Square Regression) method, this paper has conducted wind power forecast in 24 hours ahead, at Wenling wind farm which lo...

This paper investigates the uses of battery energy storage system (BESS) in ac networks highly populated with wind power generation. The investigation includes power system load leveling, frequency stabilization, and provision of reactive power support to the wind farm network. The BESS is connected to the wind farm main hub via voltage source converter, while the wind farm is connected to ac n...

This paper presents the wind farm simulation model developed in the EU-FP7 project, AEOLUS. The idea is to provide a publicly available simulation package for researchers developing farm level control solutions. With the software it is possible to auto generate a wind farm simulation model in Matlab/Simulink based on turbine parameters and farm geometry. The input to the farm simulator is power...
