ABSTRACT
 Research and use of renewable energy is becoming more active due to the demand for reduction of carbon dioxide, which is the main cause of depletion of fossil fuels and global climate change, and regulation of the generation. However, Renewable energy using sunlight or wind power has a problem that it is adversely affecting the system due to irregularity of solar radiation or wind power, or it is difficult to operate efficiently. To overcome this problem, PV ESS (Photovoltaic Energy Storage System), which is used after storing power using a battery, has been actively studied. The operation method and control method of PV ESS linked with solar power generation and ESS are proposed into single phase and three phase in this PhD thesis. In the single phase system, during the daytime, the electric power generated from the photovoltaic power generation is used to supply power to the LED lamp, charge the battery, and transmit power to the grid when surplus power is generated. In the night, the - xii - LED lamp is supplied by the power stored in the battery, and the battery is charged by the grid power in the late night. In the daytime mode, technical improvements in Maximum Power Point Tracking(MPPT) algorithm is proposed for single phase photovoltaic Energy Storage System(PV ESS). The three-phase system performs a power leveling function to improve daytime and nighttime power uneven consumption and a function to level out the irregularities of solar power generation power. Therefore, during the day when the solar power is less than the set power, the battery replenishes the power. In the nighttime, battery power is used to transmit power to the system as much as the set value to be used in the load, and the battery is charged using surplus power of the night time. In case of power failure, three phase PV ESS is used as UPS (Uninterruptable Power Supply) function. This paper will contain two major sections which are briefed below. First, a single phase 3.3kW, 600W PV ESS system is designed and a control algorithm according to operating mode is proposed. And a three phase 15kW PV ESS system is designed and a control algorithm according to operation mode is proposed. Second, the MPPT algorithm is explained and the developed MPPT algorithms is proposed. Second, there are various MPPT algorithms in the paper which are reviewed and new MPPT algorithm based the P&O(Perturb and Observe) method is proposed. The proposed algorithms is carried out in simulation and have been validated in the prototype.

PSIM Expert – Design of Power Factor Correction (PFC) converters
 Place: Stuttgart, Germany Date: September 24 – 25, 2019
 Course fees: 990 Euros* for industrial participants.
750 Euros* for academic participants.

* Instructors: – Dr. Antonio Lazaro Blanco
 Language: English
 Public and technical background required
The training course is recommended to everybody interested in the theoretical aspects and practical design issues of digital control of voltage source converters. Having previous experience in power electronics and circuit simulation is useful, but beginners with no background in those topics will also benefit from the course.
 Training Objectives The objective of the course is to acquire the fundamental competences in single-phase and three-phase PFC converters. These competences are:

 Selection of the best topology for each type of application (EV chargers, motor drives, aerospace AC/DC front-end converters and power supplies). Inductors design under the specific requirements of the PFC operation. Effective Cots inductor selection. EMI filter design. Power losses calculations and MOSFET / IGBT / Diodes selection. Dynamic analysis of dynamic modeling of PFC converters. Simple but deep understanding the PFC control loops. Effective analog and digital controller design using SmartCtrl. Effective PSIM simulation of 1-ph & 3-Ph PFC converters (including conducted EMI estimation by simulation). In addition to the topology selection, specific aspects regarding the previous competences will be shown for each type of application. Antonio Lázaro was born in Madrid, Spain, in 1968. He received the M. Sc. in electrical engineering from the Universidad Politécnica de Madrid, Spain, in 1995. He received the Ph. D. in Electrical Engineering from the Universidad Carlos III de Madrid in 2003. He has been an Assistant Professor of the Universidad Carlos III de Madrid since 1995. He has been involved in power electronics since 1994, participating in more than 50 research and development projects for industry. He holds seven patents and software registrations and he has published nearly 140 papers in IEEE journals & conferences. His research interests are switched-mode power supplies, power factor correction circuits, inverters (railway and grid connected applications), modeling and control of switching converters and digital control techniques.
