The construction of a distributed heterogeneous data platform for power grid dispatching faces challenges of diversity, large scale, and high performance. However, existing data platform design methods in both the power and computer science fields struggle to meet practical production requirements effectively. This paper constructs a distributed data storage architecture model for power grid dispatching, defining the elements and their relationships within the architecture. Additionally, it proposes methods for managing massive source data and distributed heterogeneous database clusters. Based on these findings, a power grid dispatching business data platform is designed. Test results indicate that the proposed architecture effectively supports the efficient execution of power grid dispatching business, providing a specialized data platform design paradigm for the power industry.

Under the premise of the reform of the power system, the spot market has ushered in an era of vigorous development. In the face of the complex and diverse users and electricity bill settlement methods in the spot market, this study proposes a trial calculation method of complex and multi-user electricity charges in the spot market based on concurrent computing architecture. Based on the current situation of the spot market in China, this study establishes a learning model based on Apriori algorithm to explore the relationship between different electricity bill settlement packages and multiple users in the face of different types of electricity tariff calculation methods such as fixed time-sharing, tariff and hybrid and complex and diverse user categories. According to the correlation results, different electricity packages are applicable to different types of users, so the concurrent calculation method can be established to effectively improve the efficiency of electricity bill settlement.

The Minimum -Weight Parity Factor (MWPF) decoder is renowned for its accuracy in Quantum Error Correction (QEC) for various space-time codes, including surface codes and quantum LDPC codes. This work explores the scalability of MWPF decoders through parallelization, similar to parallel MWPM decoders. We introduce a dynamic fusion graph to schedule fusion operations in dynamic quantum circuits. It allows parts of the decoding graph to be solved and fused at a later stage, without having the full fusion tree at the very beginning. It also reduces the overhead caused by the traversing of the fusion tree. The dynamic fusion graph represents a novel and efficient method for real-time QEC decoding, providing enhancements in throughput and scalability for fault -tolerant quantum computing.

We present two new assignments in the Peachy parallel Assignments series of assignments for teaching parallel and distributedcomputing. Submitted assignments must have been successfully used previously and are selected for being easy for other instructors to adopt and for being "cool and inspirational" so that students spend time on them and talk about them with others. The first assignment in this paper familiarizes students with the RAFT library for performing GPU-accelerated computation, pail of the RAPIDS AI ecosystem. Students use this library to accelerate a Radius Nearest Neighbor computation, finding all points within a given distance from a query point. In the second assignment, students parallelize a bird flocking simulation using OpenMP or OpenACC. It is a visual assignment which allows students to readily see the performance improvement.

The distributed-element transmission line model is modified to account for proximity effects in multiconductor cables and frequency dependent dielectric behaviour providing an accurate prediction of channel attenuation at broadband power line communication frequencies (1-100 MHz). The modified model is verified with scattering parameter measurements and then used as a building block for complex microgrid network modelling. Powerline communication performance tests are conducted using the HomePlug GreenPHY and HomePlug AV. The GreenPHY operates up to 450 m on star feeders and on radial feeders with long branches. However, it cannot connect reliably on radial feeders with short branches due to frequency selective notching. Functionality requires the absence of notches that penetrate below -70 dB within the band (1-30 MHz). The AV operates successfully up to 600 m on star feeders and on radial feeders with long or short branches. Due to the wide availability and low cost of the AV, it is a sensible choice for reliable broadband digital communications on microgrid networks.
