Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Thailand has established the development plan in economic, social, and environment for all terms; long-term plan (20 years), medium-term plan (10 years), and short-term plan (every 5 years). Among the terms, short-term plan is considered crucial for the national administration to realize sustainable development, especially in energy consumption. This concern has been a main problem for Thailand. therefore, the purpose of this research is to create a forecasting model in estimating short-term energy consumption. This estimation is to measure the efficiency of Thai government administration in managing the consumption under the environmental law. As of the study’s findings, it shows that in the next 5 years (2020-2024) energy consumption will rise at an increased growth. The indicated increment is found greater than a carrying capacity. Thus, this study recommends the government to form a new scenario policy on energy consumption, which does not exceed rate of 2019 capacity limit. It suggests that green technology and renewable energy should replace fossil fuel as a new approach for energy consumption in order to obtain a sustainability
This paper presents, a Particle Swarm-Optimization (PSO) using Teaching Learning-Based Optimization (TLBO), and Antlion Optimization (ALO), for tuning PI controllers of the voltage regulator and current regulator for the control circuit of Static Synchronous Compensator (STATCOM). The type of STATCOM used is a 48-pulse Neutral Point Clamped (NPC) gate-turn-off thyristor (GTO)-based Voltage Source Converters (VSC). STATCOM is compensating power of up to ±10 MVAR. STATCOM control is provided based on a decoupled current strategy (d-q) using the current direct and quadrature components. Also, STATCOM fed on the dc-link side on the VSC by the renewable energy photovoltaic cells (PV) and battery, to provide the power of compensation. The strategy of enhancing power quality in the face of system fluctuations using STATCOM with multi-supply sources Photo-voltaic cells (PV) and the battery system on the capacitor channel of VSC converters, to provide the required power of compensation. The dc to dc boost converter has been used to regulator the power of PV cells, and the dc-dc buck-boost converter circuit has been used to regulator the power of battery energy storage. Happenings of energy quality during network perturbation or disturbance, like feeder, tripping and reclosing, and load switching were analyzed with the participation of STATCOM, so the multi-source (PV and battery) system with STATCOM suppresses these problems. A modified IEEE 12 bus test feeder with STATCOM has been used for the case study. The design and analysis have been carried out using m-file and SIMULINK for MATLAB 2015b
