In this paper, standard normal cloud model is adopted to deal with the randomness and fuzziness of power quality comprehensive assessment indicators, through quantifying qualitative indicators. Taking both the subjective and objective factors into consideration, the improved multi-level interactive decision-making mode is chosen to detemine the weights of different indexes, cosidering the two-way...
Based on actual characteristic of Chinese power system, starting from the practice, this paper puts forward auxiliary service compensation mechanism designing principles in present Chinese power market. Following the spirit and the idea of provisional measures of auxiliary services management of the grid-connected power plant, combining the actual situation of wind power in China, this paper studies...
With the deepening reform to power industries, power systems are going to gradually open the demand side and the power consumers have to face the changes of their role in the market, and make a preliminary long-term forecasting for the electricity prices. In order to consider the relations between the spot market and the long-term contract market, this paper builds a multi-electricity price grey model...
The paper proposes voltage quality service, and makes comprehensive evaluation to sag energy indices to arrive at a quantitative description, then makes differential pricing of voltage quality service combined with market-oriented theory. It puts forward zonal pricing model of voltage quality service based on sag energy indices, as the foundation of comprehensive assessment of power quality and price...
With the development of electricity demand side market, large consumers have more electricity purchase choices, in the same time have to face the risk of electricity price fluctuation on different markets. In order to measure and hedge the risk reasonably, this paper introduces information entropy as the measure to risk in electricity purchase, by aid of fuzzy optimization, linear membership function...
Establishing an effective performance evaluation method and market driven incentive mechanism is an important subject that the electric power utilities are currently facing with. By aid of Data Envelopment Analysis (DEA) method which is widely used in other industries' performance evaluation, three DEA based models are proposed to evaluate electricity distribution utilities' performances, the relative...
The reliability of electricity supply is required by users increasingly, and whether to invest the reliability and voltage quality has been a point of contention. Thus, the assessment of voltage sag becomes acute. In this paper, the acceptable indices considering system performance and user characteristics are proposed for comprehensive assessment of voltage sag, including the reliability of the system...
