Abstract

In response to the imbalance of energy in the spatiotemporal dimension caused by the high penetration of new energy, a method for evaluating the hosting capacity of distributed new energy (DNE) is proposed, which takes into account the rotary power flow controllers (RPFC) and demand response (DR). Firstly, models for the RPFC and DR are developed. Then, a two-layer optimization model for the hosting capacity of DNE is established. In this model, the upper layer aims to maximize the hosting capacity by optimizing the integration capacity of new energy, while the lower layer aims to minimize the system's overall operating costs by adjusting the output of various devices. A hybrid optimization algorithm based on grey wolf optimization (GWO) and second-order cone optimization is used to solve the model. Finally, the IEEE 33-node system is used as a simulation case to analyze and validate the model under different scenarios. The results indicate that the maximum hosting capacity for renewable energy reaches 2812.2 kW in Scenario 4, an increase of 13.87 % compared to Scenario 1. Moreover, the total operational cost is the lowest among all scenarios, demonstrating that the optimization strategy can significantly enhance the hosting capacity and effectively reduce operational costs.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
