“…At the same time, T j , ΔT j , and t on maintain a dynamic state, and the dynamic parameters need to be converted into equivalent static parameters, which can produce the same degradation effect on the device. Influenced by the change of saturation volt-age drop of the IGBT collector and the thermal load of each device, the average minimum junction temperature and junction temperature fluctuation of IGBT equivalent static parameters change according to the normal distributions of 5% and 0.66%, respectively [36].…”

With large‐scale renewable energy connected to the distribution network, the traditional method to solve the distribution network voltage/var power optimization model can hardly meet the needs of online optimization of the distribution network. Therefore, a Bayesian optimization eXtreme Gradient Boosting (BO‐XGBoost) based optimization strategy for voltage/var of the distribution network considering the cost of the photovoltaic (PV) power is proposed to improve the solving speed of the optimization model. First, the voltage/var optimization model of the distribution network considering the LCOE of the PV system is established. The optimal reactive power output command data set of the PV generation in the distribution network is obtained by solving the established optimization model. The XGBoost model is used to mine the nonlinear mapping relationship between the state information of the distribution network and the optimal reactive power output of the PV system; then the Bayesian algorithm is used to complete the adaptive optimization of the hyperparameters of the XGBoost model. Finally, the PG&E 69 node power distribution system is used to verify the advantages of the proposed strategy in improving the performance of the XGBoost algorithm, increasing the solving speed of the voltage/var optimization model, and reducing the LCOE of PV generation.

- The rooftop of the University of Muhammadiyah Surabaya Integrated Laboratory building which has an area of 210 m2 can be used as a solar power plant (PLTS). Installing PLTS in buildings has several advantages, namely as a long-term energy investment and easy to integrate with the grid electrical system. PLTS is designed to save electricity consumption. In addition, if PLTS is connected to a battery, it can meet some of the energy needs at night. To design a PLTS installation in the Integrated Laboratory building, this research uses technical and economic analysis methods. Technical analysis is carried out to determine the capacity and number of PV mini-grid components required for installation. While the economic analysis aims to calculate the investment costs and the length of time for the return on investment compared to buildings without PV mini-grid installations. Based on this research, the results show that the amount of energy required for the Integrated Laboratory building is 482.148 kWh, while the planned PLTS is able to provide energy of 216,128 kWh. The PLTS design requires an initial investment of Rp. 927,700,894,-. So by using the Payback Period (PP) method, it can be concluded that the planned design is feasible, because the comparison of the cost of return on investment is 9.13 years faster than the project age that has been determined previously, which is 20 years.

Fault Management Techniques to Enhance the Reliability of Power Electronic Converters: An Overview

The reliability of power electronic converters is a major concern in industrial applications because of using prone-to-failure elements such as high-power semiconductor devices and electronic capacitors. Hence, designing fault-tolerant inverters has been of great interest among researchers in both academia and industry over the last decade. Among the three stages of fault management, compensating the fault is the most important and challenging part. The techniques for fault compensation can be classified into three groups: hardware redundancy methods which use extra switches, legs, or modules to replace the faulty parts directly or indirectly, switching states redundancy methods which are about omitting and replacing the impossible switching states, and unbalance compensation including the techniques to compensate for the unbalances in the system caused by a fault. In this paper, an overview of fault-tolerant inverters is presented. A classification of fault-tolerant inverters is demonstrated and major cases in each of its categories are explained.
