Management Index Systems and Energy Efficiency Diagnosis Model for Power Plant: Cases in China

Abstract

In recent years, the energy efficiency of thermal power plant largely contributes to that of the industry. A thorough understanding of influencing factors, as well as the establishment of scientific and comprehensive diagnosis model, plays a key role in the operational efficiency and competitiveness for the thermal power plant. Referring to domestic and abroad researches towards energy efficiency management, based on Cloud model and data envelopment analysis (DEA) model, a qualitative and quantitative index system and a comprehensive diagnostic model (CDM) are construed. To testify rationality and usability of CDM, case studies of large-scaled Chinese thermal power plants have been conducted. In this case, CDM excavates such qualitative factors as technology, management, and so forth. The results shows that, compared with conventional model, which only considered production running parameters, the CDM bears better adaption to reality. It can provide entities with efficient instruments for energy efficiency diagnosis.

Research on Power Demand Side Information Quality Indicators and Evaluation Based on Grounded Theory Approach

“…However, even if the quality of information is an important factor, most scholars prefer to focus on other aspects of DSM, such as in the economic field, billing [15], pricing [16] and cost-benefit analysis [17]; in the field of mathematics, such as scheduling [18] and planning [19], energy efficiency [20][21][22]; in the field of technology, such as renewable energy [23], smart distribution system [24] and others [25]. Some literatures considered the information quality of power information (energy information).…”

Carbon Quota and Efficiency Power Plants Implementation Decision

“…EPP and DSM are hot topics in energy management, as they grew in size, encountered economic, technological and managerial problems in development process [4]. Thus most scholars prefer to focus on the three aspects of EPPs, such as in the economic field, billing [5], pricing [6] and cost-benefit analysis [7]; in the field of mathematics, such as scheduling [8] and planning [9], energy efficiency [10][11][12]; in the field of technology, such as renewable energy [13], smart distribution system [14] and others [15].…”

Operational and Environmental Efficiencies of Japanese Electric Power Companies from 2003 to 2015: Influence of Market Reform and Fukushima Nuclear Power Accident

“…This study employs an output-oriented model for the measurement of efficiency, although the output-oriented radial model is relatively uncommon compared to the inputoriented radial model. The latter is one of the most popular methods in DEA and is used in Ji and Wang [9], Chen et al [10], Wang et al [11], Sueyoshi and Wang [12], Wang and Geng [13], and many other articles in recent publications. The basic premise of the input-oriented radial model is that inputs are proportionally contracted given a certain level of outputs, and thus, this model naturally fits with efficiency concepts for firms or other DMUs that make efforts to improve operational efficiency and strengthen cost competitiveness.…”
