During a process of energy transaction in electricity market, in order to ensure electrical safety and prevent excessively quick growth of electricity price, the concept of contract for difference (CfD) is introduced. Considering the electricity characteristics of large consumers, this paper is in the views of both generators and large consumers which sign CfDs with Grid Corporation respectively, but the signed CfDs only set rules for contract price and total contract energy in settlement period. Because market prices are different at different period, the total contract energy should be decomposed to each period for settlement of CfDs. So a CfD energy decomposition model, whose objective is to maximize social benefit, is built to settle the CfDs at each period. After running the model, the optimal result which means maximal social benefit is obtained and it is 28.1% more than that by average decomposition.

Price indicators are considered as the core of optimal allocation of resources in electricity markets. Zonal pricing can provide more flexible price signals than nodal pricing and uniform pricing, and a reasonable division of the energy market into zones is essential. In this paper, a topology based K-means clustering algorithm is developed which starts from calculating the locational marginal prices (LMPs) for a certain period of time as the characteristic values of buses and then clusters the buses characterized by similar dynamic LMPs into zones while taking the system's topology into account. Finally, the methodology is applied to IEEE-118 bus system and a realistic regional power system and the simulation results show that the developed aggregation method is effective and practical.

Worldwide energy crisis and global economic depression make reducing electricity costs has become a focus for many factory managers. This paper set up a Permutation Flow Shop Scheduling (PFSS) model with delay time, which means adding delay time between different jobs to make processing period more flexible. Considering the time of use (TOU) electricity tariff, the PFSS model using the TOU electricity tariffs is established. Meanwhile, the shutdown state is introduced for the proposed model to improve the performance. The proposed PFSS model is solved by genetic algorithm with constructing the new chromosome coding. The experiment demonstrates the new PFSS model can reduce electricity cost by 16.83% and realize the purpose to save electricity cost for factories.

Robust low-rank tensor factorization by cyclic weighted median

Low-rank tensor factorization(LRTF) provides a useful mathematical tool to reveal and analyze multi-factor structures underlying data in a wide range of practical applications. One challenging issue in LRTF is how to recover a low-rank higher-order representation of the given high dimensional data in the presence of outliers and missing entries, i.e., the so-called robust LRTF problem. The L1-norm LRTF is a popular strategy for robust LRTF due to its intrinsic robustness to heavy-tailed noises and outliers. However, few L1-norm LRTF algorithms have been developed due to its non-convexity and non-smoothness, as well as the high order structure of data. In this paper we propose a novel cyclic weighted median(CWM) method to solve the L1-norm LRTF problem. The main idea is to recursively optimize each coordinate involved in the L1-norm LRTF problem with all the others fixed. Each of these single-scalar-parameter sub-problems is convex and can be easily solved by weighted median filter, and thus an effective algorithm can be readily constructed to tackle the original complex problem. Our extensive experiments on synthetic data and real face data demonstrate that the proposed method performs more robust than previous methods in the presence of outliers and/or missing entries.

Classification of motor imagery electroencephalogram (EEG) is one of the most important technologies for BCI. To improve the accuracy, this paper introduces a classification system based on Multilayer Extreme Learning Machine (ML-ELM). In the system, the combination of PCA and LDA is chosen as the method of feature extraction and the ML-ELM is used to classify. The ML-ELM has not only the advantage which ELM has but also better performance than ELM. In the experiment, our method is compared with the methods based on ELM, such as kernel-ELM, Constrained-ELM and V-ELM, and some state-of–the-art methods on the same dataset. The experimental results show that ML-ELM is much more suitable for motor imagery EEG data and has better performance than the others.

Live-line working is an essential part in the operations in an electric power system. Live-line workers are required to wear shielding clothing. Shielding clothing, however, acts as a closed environment for the human body. Working in a closed environment for a long time can change the physiological responses of the body and even endanger personal safety. According to the typical conditions of live-line working, this study synthesizes environmental factors related to shielding clothing and the physiological factors of the body to establish the heart rate variability index RMSSD and the comprehensive security warning index SWI. On the basis of both indices, this paper proposes a security warning method and system for the safety live-line workers. The system can monitor the real-time status of workers during live-line working to provide security warning and facilitate the effective safety supervision by the live operation center during actual live-line working.

Wind power is a kind of clean and renewable energy, and it is of great benefit to utilize it in an industrial micro-grid. This paper establishes an economic dispatch model of industrial micro-grid with wind power that aims at minimizing energy costs based on scenario tree. The uncertainty of wind power and load are managed by adjusting the production schedule and unit generation schedule properly. A numerical test is taken with data of an industrial micro-grid in the paper, and the result indicates that the fluctuation of wind power and load can be mitigated by production and power generation schedule effectively and utilizing wind power can help decrease the energy costs largely. The model is also compared with the deterministic model, and some conclusions are obtained. © 2015 IEEE.

Human saccade is a dynamic process of information pursuit. There are many methods using either global context or local context cues to model human saccadic scan-paths. In contrast to them, this paper introduces a model for gaze movement control using both global and local cues. To test the performance of this model, an experiment is done to collect human eye movement data by using an SMI iVIEW X Hi-Speed eye tracker with a sampling rate of 1250 Hz. The experiment used a two-by-four mixed design with the location of the targets and the four initial positions. We compare the saccadic scan-paths generated by the proposed model against human eye movement data on a face benchmark dataset. Experimental results demonstrate that the simulated scan-paths by the proposed model are similar to human saccades in term of the fixation order, Hausdorff distance, and prediction accuracy for both static fixation locations and dynamic scan-paths.

Counting the number of differentially active S-boxes is of great importance in evaluating the security of a block cipher against differential attack. Mouha et al. proposed a technique based on Mixed-Integer Linear Programming (MILP) to automatically calculate a lower bound of the number of differentially active S-boxes for word-oriented block ciphers, and applied it to symmetric ciphers AES and Enocoro-128v2. Later Sun et al. extended the method by introducing bit-level representations for Sboxes and new constraints in the MILP problem, and applied the extended method to PRESENT-80 and LBlock. This kind of methods greatly depends on the constraints in the MILP problem describing the differential propagation of the block cipher. A more accurate description of the differential propagation leads to a tighter bound on the number of differentially active S-boxes. In this paper, we refine the constraints in the MILP problem describing XOR operations, and apply the refined MILP modeling to determine a lower bound of the number of active S-boxes for the Lai-Massey type block cipher FOX in the model of single-key differential attack, and obtain a tighter bound in FOX64 than existing results. Experimental results show that 6, instead of currently known 8, rounds of FOX64 is strong enough to resist against basic single-key differential attack since the differential characteristic probability is upper bounded by 2-64, and thus the maximum differential characteristic probability of 12-round FOX64 is upper bounded by 2-128, where 128 is the key-length of FOX64. We also get the lower bound of the number of differentially active S-boxes for 5-round FOX128, and proved the security of the full-round FOX128 with respect to single-key differential attack.
