Present status and future prospect of clean coal technology in China
Coal consumption accounts for about two thirds of the primary energy consumption in China. High economic growth has brought about a rapid increase of coal consumption. Low-efficiency combustion of a large amount of coal caused coal-smoke related air pollution. The Chinese government put forward plans to develop clean coal technology in the early 1990s, and has listed it as one of the emphases for ...

Size optimisation of hybrid wind-PV power generation systems for remote rural areas
Electrical power generation with renewable energies, such as wind and solar, plays an important role in the electrification of remote rural areas. Since there are always seasonal and synoptic variations in wind and solar resources, a hybrid system, consisting of both wind and solar energy, may be more reliable and economical than a single energy system: this is because either energy can ...

Reactive power compensation of wind energy conversion system by using Unified Power Flow Controller
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. The WECS is a fixed speed/constant frequency system that is equipped with an induction generator driven by an unregulated wind turbine. The problem is viewed from short-term (10 seconds), mid-term (10 minutes) and long-term (48 ...

Reactive power compensation strategies for wind generation in distribution systems: a power quality approach
This paper studies the impact on the voltage profile of wind energy based generators connected to distribution power systems. Voltage fluctuations arise in distribution levels including noncontrollable primary energy sources because of their corresponding active power injection variations. A number of reactive power strategies have been analysed and compared focusing on the voltage fluctuation ...

Analysis and experimental verification of a control scheme for unified power quality conditioner
Improving power quality for sensitive load by a Unified Power Quality Conditioner (UPQC) in a distributed generation system is presented in this paper. The power balance of a UPQC, consisting of back-to-back connected series and shunt Active Filters (AF), is analysed. Based on the analysis a novel control scheme is established in a 2-phase Synchronous Rotating d-q Frame (SRF). In this control ...

Impacts of dynamic reactive power compensation devices on the performance of wind power generators
This paper investigates the main impacts of dynamic reactive power compensation devices on the performance of induction machine-based wind power generators. The dynamic reactive power compensation devices analysed are the SVC (Static Var Compensator) and the DSTATCOM (Distributed Static Synchronous Compensator). The usage of these devices as a power factor regulator or a voltage regulator is ...

Mitigating CO2 emissions by adjusting the power generation mix in Taiwan
In this paper, we employ a multi-objective programming model to estimate the power generation mix trade-off between generation costs and CO2 emissions in Taiwan. Eight policy scenarios are simulated and compared to the reference and base cases. The empirical results show that, for the electricity sector, CO2 emissions in 2010 could be set at 120% of the 1990 level, by way of promoting ...
