This paper deals with load optimal dispatching among power plant units in the context of electric power market competition environment. The multi-agent evolutionary algorithm (MAEA) is specially useful in load optimal dispatching, the model of which is set up based on characteristic curve of the generator coal consumption approached by quadratic function. In particular, the following restraints are...
Following the steady demand growth and diminishing generation capacity margin due to lack of generation investment, Slovenia is already importing almost a quarter of electricity needed to cover its demand. Coupled with the deregulated electricity market and the European Union (EU) climate change mitigation measures implemented through EU Emissions Trading Scheme (EU ETS), the economic as well as environmental...
The distributed generation (DG) acts an important role in the reliability of electric power system. In power market, with the rapid development of DG in recent years, it is necessary to discern and calculate the value of possible economic contract between the DG and the integrated main power grid, in which the DG and the main grid serve as reserve capacity for each other. The problem of possible options...
In this paper, the city input-output efficiency analysis which includes electric power input has been done based on the extension models of DEA to Chinapsilas typical cities. At first, it established index system of comprehensive evaluation of city efficiency, and did input-output-effectiveness evaluation which include electric power input for China's 23 cities in 2006 and sorted by the urban development...
The city is playing an important role in the social economic development. The research on influencing factors, formation mechanisms and problems in the development of cities, especially the relationship between urban electric power and economy growth, is significant to make urban development strategy and complete the urban electric power planning. In this paper, based on the maximum entropy method,...
Because power loads are influenced by various factors, and the changes of power load presents are complicate, the traditional forecasting methods are always not satisfied. According to the random-increase and non-linearity fluctuation of residual series, gray neural network forecasting can reflect the increase character and non-linearity relationship. This paper using the improved ACO method as the...
With the continuous deepening of the power system reform and the blackouts of someplace on the world, the safety of the power grid has received high attention from all sections of the society. The former researches on the power grid safety are mostly about special parts, the method to estimate the whole power grid safety should be improved in the future. In this paper, according to the characters...
Wind power concession refers to the way of selection of the owner of concession - the concessionaire by bidding, which is mainly carried out by local government with wind resources or its authorized company to delimit a wind resource district with commercial development value. In this paper, strong supporting degree and low effectiveness of the concrete terms of current Chinese policies, laws and...
Analysis of regional power demand cycle is the foundation of researching the national power demand cycle. Firstly the growth rate data of power demand in China from 1994 to 2005 is dealt with the H-P filter, and the periodicity factors of the nation and provinces power demand are obtained. Secondly the periodicity factors of the provinces power demand are treated with cluster analysis, and the problem...
The paper proposes short-term power load forecasting model based on fuzzy RBF neural network, it has overcome the BP algorithm's disadvantage of slow convergence rate and it fall into partially the smallest insufficiency easily. RBF network model in the use of the latest neighborhood clustering algorithm, and the network structure and the parameters are double-adjusted and the training speed and forecast...
This paper optimizes the wavelet neural networks with genetic algorithms which has the optimization of the overall search capabilities, and establishes the model of wavelet neural networks based on genetic algorithms. It overcomes the shortcomings of BP neural network for their own, and it can get higher accuracy and faster convergence. The examples also show that the model can improve forecast accuracy...
An improved BP Neural Network with additional momentum and adaptive learning is proposed in the paper to predict the growth rate of electricity consumption in China. Matlab7 is used as modeling tool to design the model. Current year GDP growth, electric power consumption growth and growth rate of secondary industry are taken as input variables while next year electric power consumption growth is predicted...
This paper analyzes the strategic options of the responsibility of the state grid companies and the government to prevent the crisis of large area blackout with the game theory, and also the results have been verified with examples. It arrives at the low efficient Nash Equilibrium tactics that the leaderships of the Power Grid Corporation don't participate in the prevention and the Government does...
This paper investigates the effect of debt financing in electric power listed company through an empirical research with the regression analysis method. According to the capital structure theory, the effect of debt financing lies in financial leverage effect, the tax shield effect and the company governance effect. Considering the characteristics of the electric power industry, we makes a detailed...
Through the statistical analysis of 51 electric power listed company, this paper shows the specific industry characteristics in electric power listed company, and makes detailed study on the electric power listed company's effect, tax shield effect and corporate governance effect of debt financing, then use empirical method to prove them. The empirical results show that, for the electric power listed...
