The Indian power system underwent two separate massive blackouts on 30th and 31st of July 2012. These blackouts exposed a series of inherent problems underlying the power system of India, such as its generation planning, transmission planning, grid infrastructure, management systems, primary energy resources, environmental constraints, electricity market, and information technology, which together aggravate the massive blackouts.

  • [Energy] Primary energy congestion of power systems

    Primary energy has the potential to bring challenges to the reliability, economic, and eco-friendliness of global electric power systems. The concept of electric power security are proposed, including many factors that are not considered in power system reliability analysis, such as coal supply for power system, fuel price for electricity power market, carbon emissions of power generation, and so on. It is broader than power system reliability and security, which means that providing energy in the form of reliable, economical, and eco-friendly electric power. Following an account of existing blackout defence methods and systems, the processes of transforming various kinds of primary energy into electric power and the interactions between them are described, particularly with regard to flows of energy, capital, and information. Factors that limit the liquidity of these flows are defined as “generalized congestion”, and the challenges presented by primary energy are named “primary

  • [Energy] Wind speed equalization-based incoming wind classification by aggregating DFIGs

    With the development of wind energy, it is necessary to develop equivalent models to represent dynamic behaviors of wind farms in power systems. The equivalent wind method is investigated for the aggregation of doubly-fed induction generator wind turbines. The detailed procedures for the calculation of equivalent wind are analyzed. The necessity of classifying incoming winds is shown. To improve the performances of the method, incoming winds are classified according to mean wind speeds and positive/negative semi-variances of wind speeds, and a group of turbines with similar incoming winds are aggregated together. The effectiveness of the method is verified through simulations in MATLAB/Simulink.
