Arithmetic coding based lossless compression schemes for power system steady state operational data

Research on battery data compression method for electric vehicles

“…Lossless compression algorithm is divided into statistic compression algorithm and dictionary compression algorithm. Huffman coding algorithm is based on statistic compression algorithm, and most representative lossless data compression algorithm (Chlopkowski and Walkowiak, 2015;Das and Rao, 2012;Nakatsuka et al, 2013). This algorithm encodes data based on the probability of the character.…”

Development of cloud‐based power system operational data management system

“…Feature-based load data compression [12] gives higher compression ratio (CR) than resumable load data compression algorithm (RLDA) while compressing load profile information. Four schemes based on four variants of the arithmetic coding are proposed in [13] which are used for compressing the hourly data collected from Southern regional LDC (SRLDC). RLDA [14] proposed for compressing load profile data generated by smart meters can also effectively compress practical power system operational data [15].…”

Development of lossless compression algorithms for power system operational data

“…Validation of such models is possible only when a detailed measurement of power system operational data is available. Storage and retrieval of data associated with the power system is a challenging task [2]. Data compression is extremely popular for the applications dealing with a large volume of data as it reduces data volume and enables better utilisation of bandwidth.…”

“…Available works on power system monitoring data compression [2][3][4][5] employ single or multiple lossless or lossy compression techniques. As no loss of information is desirable, the lossless algorithm must be employed for compressing monitoring data.…”
