In power market, accurate electricity price forecasting can help all market participants make optimal bidding or purchasing decisions and maximize their revenue. In recent years, much attention has been focused on the short-term electricity price forecasting. Based on the theory of ARMA-GARCH model, the paper divides the constant day series into working day series and holiday series. Then the models...
Transmission and distribution networkpsilas natural monopoly characteristic decides it must receive regulation. Based on the analysis of price-cap regulation model, combining with the situation and status of power network in China, this paper put forward a reformative price regulation model, which takes network expansion and service quality into account at the same time. To carry out the transition...
Loan risk pricing system of the bank is the core of interest rate marketization. Realizing independent pricing of loan interest rate will be an inevitable tendency. At present, commercial banks of China have widely developed credit rating system for customers. And it is a question which must be solved urgently that how to carry on risk pricing of loan interest rate and determine market competition...
The electric power industry is regarded as the basic industry of national economy, which makes it unable to get rid of the governmentpsilas regulation, as well as its own technology and economic characteristic. After reforming of regulation, government pays a good deal of attention to the performance-base regulation which has been used in telecommunication successfully and can solve the low efficiency...
This paper considers a supply chain model in which a single supplier sells a single product to a single retailer who faces the newsvendor problem. The retailer has combined decision bias. The results show that the supply chain can achieve channel coordination with return policy, the return price increases as the retailerpsilas waste-averse preferences increases and decreases as stockout-averse preferences...
Through collecting official statistics as much as possible, 2005 social accounting matrix (SAM) of China is built up. Based on the 2005SAM, the method of matrix multiplier is adopted in the analysis of the impact of electricity price adjustment on the departments of national economy and the quantification of the impact. It is revealed that the impact of multiplier on capital account (the expenditure...
With the liberalization of electric market, the customers may have different reliability requirements, which generates different reliability costs to the grid company, that means they should afford different reliability price. An integrated electric power supply reliability differential pricing model was presented considering both the reserve costs and distribution and transmission investment costs...
A framework of combining importance sampling with Structured Database Monte Carlo strategy is developed. The proposed method attempts to devise a generic method for designing importance sampling method. Firstly, evaluation function and objective function are expressed in a way that there is a linear relation between response estimator and majorized function. Order structure is imposed not only on...
There are a number of residences with low income in China that cannot afford the current electricity price. The lifeline electricity price is the price that the government set up to satisfy the basic living demand for low-income group. This paper aims at these people, the urban and rural, tries to develop a model of lifeline electricity price and consequently gives some suggestions for government.
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...
Power generation adequacy is critical for the reliability of electricity supply service, and therefore its investment draws much attention. This paper builds a dynamic simulation model to solve the setting of two key parameters, the energy price cap and the capacity price in the generation market, and applies this model to various cases to analyze the generation capacity development. Based on the...
Since the second half of 2007, the coal price in China has witnessed dramatic growth, the generation cost has gone up and power generation companies have got huge benefit losses. This essay analyzes the major reasons of coal price increase in China, predicts the future tendency of steam coal price and proposes policy suggestion to deal with rapid growth of coal price.
Electricity futures exchange is usually regarded as a valuable way to reduce price volatility of electricity market, but its risk to the equilibrium of the market is almost neglected; therefore, it is impossible to find out a workable approach to avoid the impact from supply and demand to electricity market. However, it is so important that it should not be avoided. In view of the case, this paper...
This paper provides the evaluation method and model of the externality of the transmission projects, and identifies both negative and positive externalities, as well as makes quantitative and qualitative analysis of externality. In order to quantify the impact of transmission construction projects on the power flow distribution, power supply and demand, as well as the power price of the neighboring...
