Abstract

High-quality power demand side information is necessary for scientific decision-making of power grid construction projects. Literature research shows that the current demand side management (DSM) information quality theories and methods need to be improved, and the information quality indicators and evaluation work are essential. In this paper, based on the grounded theory, about 250 copies of relevant literatures and interview records are reviewed. Through open coding, spindle coding, and selective coding, 105 initial concepts are finally extracted to 35 categories and 10 main categories. On this basis, four information dimensions including load extraction, monitoring, management, and government planning are summarized. An index system containing 34 indicators for DSM information quality evaluation on the power demand side is constructed. Finally, using matter-element extension evaluation method, a case study in China is performed to verify the feasibility and scientificity of the indexes. The results show that DSM information quality evaluation indexes are effective, and the evaluation method is also applicable. The establishment of DSM information quality indicators and the evaluation methods in this paper can provide a reference for similar information quality evaluation work in power systems.

Building DSM Information Quality Evaluation Indexes Based on the Grounded Theory
We searched the above repository with the keywords “power demand side management”, “power demand side information quality”, “power demand side response”, “power/grid information quality”, and “power load”, with a total time frame of 168 qualitative materials after 2013; secondly, the materials obtained were screened by initial reading, and the screening criterion is the evaluation of electricity demand information quality by users or professionals

Summary

Introduction

Demand Side Management (DSM) is to allow enterprises and users to manage their own electricity consumption by building a refined power management platform. Over the past 10 years, the development of DSM has achieved abundant energy conservation and emission reduction effects and formed a certain scale. The State Grid Energy Research Institute of China counts that the generation capacity of DSM project is 640.7 billion kWh in China for 2011–2015, and estimates for 2016–2020, it is 1.3254 trillion kWh. For example, the State Grid Energy Research Institute of China counts that the generation capacity of DSM project is 640.7 billion kWh in China for 2011–2015, and estimates for 2016–2020, it is 1.3254 trillion kWh It can reach 1.9661 trillion kWh during the period 2010–2020, equivalent to a reduction of 22,598 kWh in generation capacity, and nearly 57 billion USD in investment compared with the conventional power plants [1]. With the increase of DSM project scale, many problems in management have been exposed [2]
