Research Overview<\/strong><\/em>
The end points of power systems consist of single-phase AC distribution lines; however, single-phase AC cannot achieve synchronous stability. Conventional technologies have limitations when it comes to utilizing single-phase power sources, such as solar power generation, during disasters. Our laboratory has developed a new inverter, the \u201cSingle-phase Synchronous Inverter (SSI),\u201d to solve this problem, with the goal of creating a more resilient power system. Using this SSI, we are conducting technical development\u2014including the design of internal control systems for inverters\u2014to build a single-phase microgrid (SMG), while simultaneously conducting demonstration tests using the Research and Education Building of the Faculty of Engineering at Hiroshima University as a model.

Research Overview<\/em><\/strong>
From the perspective of carbon neutrality, attention is focusing on variable renewable energy (VRE) sources. However, VRE output is subject to uncertainty due to weather conditions, necessitating the stabilization of power supply through planned output control. Accurate forecasting enables more efficient operational planning for existing thermal and hydroelectric power plants, as well as stationary battery energy storage systems (BESS) and electric vehicles (EV). In this laboratory, we are developing PV and electricity load forecasting methods using AI and machine learning. We are proposing robust supply-demand planning methods based on these forecasts, as well as real-time operation methods based on the concept of the feasible region. Furthermore, we are developing a comprehensive supply-demand control simulator (Power Supply-Demand Manager) necessary for energy management through advanced supply-demand control using model predictive control.

Research Overview<\/em><\/strong>
When large-scale solar power generation is introduced into a power system, issues related to supply reliability\u2014such as insufficient regulating capacity to absorb output fluctuations and voltage regulation in distribution systems, as well as frequency fluctuations\u2014have been identified. Currently, the N-1 reliability standard is adopted worldwide. In grid operation, the N-1 standard requires meeting constraints such as overload, voltage upper and lower limits, voltage stability, transient stability, and frequency variation (supply-demand balance constraints). The operating region (generator output range) that satisfies this N-1 reliability standard is called the Static Security Region (SS Region) and is defined at a specific time instant. Next, taking into account prediction errors in solar power generation, we defined the operational region where reliability is maintained even in the presence of uncertainty in these variable parameters as the Robust Static Security Region (RSS region). Our laboratory has proposed a new reliability metric that incorporates transient stability analysis and the range of uncertain output from solar power generation.<\/p>\n\n\n\n
