Designing interruptible load management scheme based on customer performance using mechanism design theory

Xuehui Jian, Li Zhang, Xiaofeng Miao, Yumin Zhang, more

International Journal of Electrical Power & Energy Systems > 2018 > 95 > C > 476-489

Interruptible load management (ILM), as an important incentive-based demand response (DR) program, plays a critical role in power system operation. An improved ILM scheme design method is proposed in the paper. From the perspective of social welfare, the scheme design is described as an optimization problem, and then mechanism design theory is adopted for solving. The novel idea presented in the paper...

A novel analysis and forecast method of electricity business expanding based on seasonal adjustment

Yumin Zhang, Xueshan Han, Guangsen Yang, Yong Wang, more

2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC) > 707 - 711

2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)

Inefficient utilization of electricity business expanding data in State Grid Companies related departments still exist. It is because of their excessive attention on the speed of electricity supply and the quality of service, but ignores the potential useful information of the data implied in the future electricity sale market. With this regard, this paper proposes a novel analysis and forecast method...

Short-term wind power combined forecasting based on error forecast correction

Zhengtang Liang, Jun Liang, Chengfu Wang, Xiaoming Dong, more

Energy Conversion and Management > 2016 > 119 > C > 215-226

With the increasing contribution of wind power to electric power grids, accurate forecasting of short-term wind power has become particularly valuable for wind farm operators, utility operators and customers. The aim of this study is to investigate the interdependence structure of errors in short-term wind power forecasting that is crucial for building error forecast models with regression learning...

Error estimation of statistical baseline load methods

Xiaofeng Miao, Li Zhang, Yumin Zhang, Xueshan Han

2015 IEEE Power & Energy Society General Meeting > 1 - 5

2015 IEEE Power & Energy Society General Meeting

Customer baseline load (CBL) is widely used as an evaluation tool in demand response (DR) programs. Due to uncertainty of load, it is difficult to establish an accurate CBL model and the calculation error is inevitable. Therefore, calculation error of CBL must be estimated, so that DR programs can be evaluated effectively. Consumers' load changes with periodic pattern of production and life, meanwhile,...

Algorithm for Information Hiding in Optional multi-Text

Yuanzhong Shu, Lei Liu, Weina Tian, Xiaofeng Miao

Procedia Engineering > 2011 > 15 > Complete > 3936-3941

For the limitation of small redundancy and small amount of hiding information in text documents, especially in plain text documents, hiding information in plain text document is a difficult problem to solve. Most majority of the algorithms based on text document have been adopted the form of single text segment, of which the security is unpromising. This paper proposes an alternative multi-text information...

Differential Evolution based on adaptive mutation

Xiaofeng Miao, Panguo Fan, Jiangbo Wang, Chuanwei Li

2010 2nd International Asia Conference on Informatics in Control, Automation and Robotics (CAR 2010) > 3 > 113 - 116

2010 2nd International Asia Conference on Informatics in Control, Automation and Robotics (CAR 2010)

Differential Evolution (DE) is a novel evolutionary computation technique, which has attracted much attention and wide applications for its simple concept, easy implementation and quick convergence. In order to enhance the performance of classical DE, a new DE algorithm, namely AMDE, is proposed by using an adaptive mutation. In AMDE, the mutation step size is dynamically adjusted in terms of the...

Design of Compact Frequency-Tuned Microstrip Balun

Xiaofeng Miao, Wenmei Zhang, Yanfeng Geng, Xinwei Chen, more

IEEE Antennas and Wireless Propagation Letters > 2010 > 9 > 686 - 688

In this letter, a compact frequency-tuned microstrip balun with a ring structure is proposed. By tuning the capacitance of varactor, the operating frequency of the balun can be tuned continuously. Also, by arranging the two loops on two layers, the difficulty in process caused by narrow gap can be avoided. Meanwhile, by introducing the lumped capacitors, the dimension of the balun is reduced greatly...

A Hybrid Differential Evolution for Numerical Optimization

Xiaofeng Miao, Dejun Mu, Xingwen Han, Degang Zhang

2009 2nd International Conference on Biomedical Engineering and Informatics > 1 - 5

2009 2nd International Conference on Biomedical Engineering and Informatics (BMEI)

Differential evolution is a well-known optimization technique to deal with nonlinear and complex problems. However, it suffers from some difficulties, such as expensive computation, problem-dependent parameters, etc. In order to tackle these problems, this paper presents a hybrid DE algorithm, called SAODE, by employing opposition-based learning (OBL) and a self-adapting mechanism to adjust parameters...
