Evaluation of power enterprise has becoming a focus of electricity industry since market reformation. Operation datum of nine subsidiaries of Inner Mongolia Power Group Co., Ltd was collected. Indexes weights were obtained by AHP. Considering experts' preferences, it is more reasonable to view weights as random variables. Assessment values of sample were calculated by simulation. Rule ensembles algorithm...
The paper conducted a stakeholder analysis for establishing a centralized biogas plant in Yangling, Shanxi province, China. Stakeholder positions in material flow system and their inter-relationships in the project were reviewed. Their interests and concerns of the project were further analyzed. The results revealed that lack of coordination among the indirect stakeholders, who enforced environmental...
This paper will study the A-J Effect and the strategy of the Power Company under dynamic game of incomplete information. We will research the dynamic game of information between the regulatory agencies and power companies, and then we conclude that the optimal strategy of Power Company is not to make excessive capital investment. The regulated assets, debt ratio and the extra cost will limit the Power...
This paper presents a scenario where wind and wave energy conversion techniques are collocated, enhancing per unit energy cost. Wave energy is one of the largest renewable resources in the world, but is largely untapped. By capitalizing on the already proven structural components of offshore wind conversion systems, efficient wave turbines could be implemented for lower total cost, and lower per unit...
The bidding strategies of the generation companies in electricity markets is a research hotspot which requires applications of game theory. This paper reviews the research status of bidding strategies of power suppliers and the pricing rules in electricity markets. The paper is mainly composed of two parts. The first part is to introduce the bidding models of power producers based on the oligopoly...
Nowadays, Demand Response (DR) comprehensive benefits assessments focuses on the economic benefits but overview the consideration of social benefits. The paper based on the contacts of DR and Corporate Social Performance (CSP), assessing the comprehensive benefits of DR projects from the CSP perspective of power companies, showing the conclusion that DR project can be effectively promoted by combining...
Problems which appeared in regulated electricity supply systems led to the introduction of deregulated systems. The problems encountered with deregulation led to a general understanding that in the electricity market, government should not withdraw its supervision.
The paper endeavors to assess the extent of technical efficiency, pure technical efficiency and scale efficiency of Indian thermal power plants at unit level. Result shows that there is no significant degree of difference in scale efficiency. Managerial inefficiency is the main source of overall technical inefficiency. The results pertaining to Tobit analysis reveal that regional differential and...
Nowadays, renewable and clean energy resources developments become the urgent requirement of global economy because of the severe traditional energy crisis. The electric power enterprise is one of the important enterprises to develop and use energy. So, more and more electric power enterprises focus on new energy power investment. In this paper we discuss the economic evaluation of new electrical...
In power systems, the interruptible load management (ILM) plays an important role in boosting demand responses, which can help a power system operator solve a variety of problems. A critical issue is the incentive paid to the consumers to participate in the ILM. It is widely recognized that integration of consumers' willingness to curtail load in the ILM is helpful to improve the allocation efficiency...
In recent year, with the marketization reformation of electricity continuously and deeply perfecting, power market of consumer will be opening-up step-by-step. Large electricity consumers could purchase electricity in both long-term contract market, interruptible contract market and spot market. Also, they can choose to purchase electricity directly from self-supply power plant. Under such circumstances...
This paper analyses the main reasons of yield risks, combined with the tariff recovery problems and the particularity of electricity market in power enterprises. Relative measures and methods are proposed to lower yield risks according to the analysis results. Besides, a yield risk management control evaluation system is established combined with Risk Control Theory. The management control measures...
Implementation of time-of-use (TOU) is one of demand-side management measures, will help load shifting, energy saving, its effect is dependent on science episodes and appropriate TOU. Based on the shared interests of energy conservation and the goal of establishing a TOU optimization model to arrive at the most time into their corresponding TOU pricing.
AMERICAN Electric Power (AEP) is one of the largest electric utilities in the United States delivering electricity to customers in 11 states: AEP East (Indiana, Ohio, Michigan, Virginia, West Virginia, Kentucky, Tennessee) and AEP West (Arkansas, Louisiana, Oklahoma and Texas). AEP is a member of three Regional Transmission Organizations/ Independent System Operators: PJM Interconnection, SPP (Southwest...
Total losses in transmission and distribution (T&D) of electrical energy including nontechnical losses (NTL) are huge and are affecting the good interest of utility company and its customers. In this context, importance of customer load profile evaluation for detection of illegal consumers is explained in this paper. Classification of the customers based on load profile evaluation using SVMLIB...
Distribution pricing scheme and tariff structure has been changing during the past decades all over the world. This paper introduces the transition and current situation of distribution pricing scheme as well as tariff structure in China. The price scheme is firstly introduced by dividing the time span into two phases, before and after 2005. Then, the tariff structure is described and compared from...
The paper presents an agent-based approach to model the flexibility of the demand-side. It uses Q-learning algorithm to model a behavior of a demand-side agent, so to investigate the elasticity of the demand to the change in price. Often, market simulation models assume that the demand elasticity is known, however due the lack of data this elasticity is not easy to determine. The objective of this...
“Critical Peak Pricing(CPP)” refers to a method of pricing electricity whereby "Time of Use (TOU)Pricing" is in effect with the exception of certain "peak periods" at which time electric prices may reflect the costs of generating and/or purchasing electricity at the wholesale level[1]. It aims to reduce load during the relatively few, very expensive hours more dynamically. In CPP...
In this paper we present an investment problem where a decision maker from a company has to decide on the best among four possible alternatives of power supply. Two of these alternatives are related to investment in a thermal generator to produce electricity for the company own use. In this framework there are many uncertainties that have strong influence on the net present values of each alternative...
Demand side management will be a key component of future smart grid that can help reduce peak load and adapt elastic demand to fluctuating generations. In this paper, we consider households that operate different appliances including PHEVs and batteries and propose a demand response approach based on utility maximization. Each appliance provides a certain benefit depending on the pattern or volume...
