A big data framework for short-term power load forecasting using heterogenous data by Haibo ZHAO, Zhijun XIANG, Linsong XIAO

“…The power system is in a transition towards a more intelligent, flexible and interactive system with higher penetration of renewable energy generation, load forecasting, especially short-term load forecasting for individual electric customers plays an increasingly essential role in future grid planning and operation.A big data framework for short-term power load forcasting using heterogenous was proposed, which collected the data from smart meters and weather forecast, pre-processed and loaded it into a NoSQL database that was capable to store and further processing large volumes of heterogeneous data.Then, a long short-term memory (LSTM) recurrent neural network was designed and implemented to determine the load profiles and forecast the electricity consumption for the residential community for the next 24 hours.The proposed framework was tested with a publicly available smart meter dataset of a residential community, of which LSTM’s performance was compared with two benchmark algorithms in terms of root mean square error and mean absolute percentage error, and its validity has been verified.…”

Multi-source data security protection of smart grid based on combination key by Jian GAO, Wenbin CHEN, Jianmin PANG, Huadong YU, Guorui SONG

“…As an important infrastructure of power system,power communication network has deployed a large number of widely distributed business terminals and communication terminals,whose data security is related to the safe and stable operation of the entire power network.In order to avoid the situation that the information cannot be safely exchanged due to the shortage of keys.The sharding and combination technology based on keys was proposed to realize the expansion of limited keys,so as to solve the problem of a large number of keys needed for multi-node and mul-ti-service.Firstly,a sharding scheme was obtained according to different conditions.A key was divided into several dif-ferent sub-key pieces,and then a new key was generated by combining these key pieces and distributed to different ter-minals in the system.A large number of combined keys generated were conducive to update key ,which could ensure the data service “one at a time” and effectively enhance the communication system's ability to resist damage and invasion.Through analysis and calculation,the effectiveness of this method in realizing real-time update of a large number of ter-minal business keys with limited keys was further verified,and data secure communication was realized.…”

Sensitivity Analysis of Power Regulation Parameters for Doubly-Fed Pumped Storage Units by SUN Maoxiang, WANG Liying, WANG Dakai, FAN Honggang, ZHANG Jiajie, WANG Zeyang

“…This paper aims to investigate the impact of power regulation controller parameters on the system's control performance of doubly-fed pumped storage units.Based on the power regulation control strategy,the paper employs an orthogonal experimental design to analyze the sensitivity of power regulation controller parameters.Four parameters in the power regulation controller (each parameter selected at 4 different levels) are subjected to orthogonal design.Integral of time-weighted absolute error (ITAE) is chosen as the optimization objective.Stable operating conditions are identified through range analysis.The sensitivity of parameters is quantified by range analysis to distinguish the major and minor parameters affecting the control performance of the system.The computational results demonstrate that a smaller ITAE value indicates higher dynamic response quality of the system,smaller errors,and faster convergence speed.The proportional coefficient of the current regulation module significantly influences the control performance of the system.However,the integral coefficient of the power regulation module,the integral coefficient of the current regulation module,and the proportional coefficient of the current regulation module have a relatively minor effect.The sensitivity analysis of power regulation controller parameters provides a theoretical foundation for the reliable operation of doubly-fed pumped storage units in the power system.…”
