This paper discusses the environmental effects of incorporating wind energy into the electric power system. We present a detailed emissions analysis based on comprehensive modeling of power system operations with unit commitment and economic dispatch for different wind penetration levels. First, by minimizing cost, the unit commitment model decides which thermal power plants will be utilized ba...

Due to the volatile and correlated nature of wind speed, a high share of wind power penetration poses challenges to power system production simulation. Existing power system probabilistic production simulation approaches are in short of considering the time-varying characteristics of wind power and load, as well as the correlation between wind speeds at the same time, which brings about some pr...

Future energy demand and increasing carbon emission requires an alternative source of energy. In recent few years, Use of DFIG based wind farm increased tremendously, thus effect of wind penetration on small signal stability of existing multi machine system need to be analysed. In This paper effect of penetration of wind turbine with DFIG on stability performance of the IEEE 9 bus and 39 bus sy...

Wind farms usually produce power irregularly, due to unpredictable change of wind speed. Accordingly, we should determine the penetration limit of wind power to consider stability of power system and build a facility to control the wind power. The operational limit of wind power is determined as the minimum between the technical limit and the dynamic limit of wind power. The technical limit is ...

This paper focuses on PSS/E modeling of wind farms of Doubly-fed Induction Generator (DFIG) type and their impact on issues of power system operation. Since Wind Turbine Generators (WTG) don’t have the same characteristics as synchronous generators, the appropriate modeling of wind farms is essential for transmission system operators to analyze the best options of transmission grid reinforcemen...

This paper deals with the study of power quality in an isolated system with high wind energy penetration level. An induction wind plant, a ynchronous power plant and a network constitute the analysed system. The work focuses on studying the effect of mechanical power from wind n load voltage and network frequency fluctuations. A linear model for the complete system is proposed in order to use e...

This paper is a part of a research project to study the dynamics and control of distributed resources (DRs) in the deregulated electric power industty’. It reflects the need to look at large wind farms as power plants, as a result of the increased penetration of wind energy in the power systems many places in the world. To obtain an optimal integration of high penetration of wind energy in the ...

Although capacity credits for wind power have been embodied in power systems in the U.S. and Europe, the current planning framework for electricity in China continues to treat wind power as a nondispatchable source with zero contribution to firm capacity. This study adopts a rigorous reliability model for the electric power system evaluating capacity credits that should be recognized for offsho...

In the scenario of energy and environmental crises that we are facing today, integrating renewable sources of energy with the existing power grids is rapidly becoming the most obvious solution. Harnessing electricity from wind is a promising option that has lately attracted attention and research funding worldwide. However, increasing wind power penetration still remains a daunting problem star...
