“…PV grid-tie inverter is designed with an anti-islanding mode that prevents power from the inverter being transmitted to the grid when the grid is disconnected. As a consequence, local load will be interrupted indiscriminately, which incurs unnecessary outage following the grid outage [7]. Hence, the optimization of energy is not fully utilized though the source is ready and available.…”

The variability of solar irradiance caused by weather conditions could result in the mismatch between the solar PV generation and demand, particularly in the microgrid context. This may lead to detrimental effects of over/under voltage or over/under frequency. In this regard, this paper presents the laboratory setup of a grid-connected PV inverter operating in islanding condition. To achieve this, a load control algorithm is proposed to provide autonomous real time demand control that follows the PV generation to maintain generation-demand equilibrium requirement. Laboratory results show that the proposed load control algorithm is capable to address the voltage and the frequency violation in islanding condition, regardless of the variation of irradiance and power generated by the PV sources.

“…One of the attractive DERs is the PV sources as they have advantages include; everywhere availability, zero carbon dioxide emission, and low running and maintenance cost [4]. Moreover renewable energy sources (RESs) give each nation energy dependency by reducing the energy and fuel required to be imported.…”

Abstract-High photovoltaic (PV) integration in electrical grid is one of the strategic goals for many countries nowadays. That's why many governments introduced incentive policies seeking for PV projects funded by private sector. These kinds of projects have to be a positive net present value (NPV) in order to get sponsorship by non-government sector. This paper investigates the PV solar system financial analysis in Malaysia and Turkey. In developing counties, the governments are looking for more renewable energy (RE) sources installation. Thus, they implemented Feed-in Tariff (FiT) mechanism to accelerate investment in renewable energy technologies. As the efficiency of the PV cell increases and the cost/Wp decreases with time, the expected net present value (NPV), return on investment (ROI) and payback period for the PV system are going to achieve a significant increase. The FiT rate in Malaysia is significantly higher than Turkey and the purchase agreement is longer. These advantages would make Malaysia a better place for PV system investment. Moreover, this paper proposed the PV system to be installed at the roof of building, merged with another suitable business such as; roller skating rink or cafe. This combination makes the PV project making income at day time via solar radiation, while generating income at evening and night time via the other business. The analysis results revealed that, the combination of PV system with roller skating rink or cafe can reduce the payback period and make a wonderful combination between green energy and people.

“…They represent an evolution toward a more optimized and sustainable energy system using the implementation of information technology (Fang et al 2011;Hashmi et al 2011;Kezunovic et al 2012;Shamshiri et al 2012 High viscosity silver paste (REXALPHA RFS156 (prototype), TOYOCHEM CO., LTD.) was used to prevent contacts between the adjacent silver paste lines. The viscosity is about 270 Pa s at 5 rpm as read by an E-type viscometer.…”

Development of thin film based flexible current clamp sensor using screen-printed coil

successfully provide accurate information for real-time monitoring and control of the entire distributed power system. Especially, it is important to develop a high-volume manufacturing technology employing small size and inexpensive sensors. Currently, there are various current sensors (Ziegler et al. 2009), and they have been developed as small, lightweight and low-cost units (Votzi et al. 2011;Moghe et al. 2012). However, a thin film based flexible clamp-type current sensor has yet to be made.We had reported in our previous studies, a flexible current clamp sensor was fabricated by thin film materials and screen-printed coil ( Fig. 1), and a novel fabrication process of the sensor using a reel-to-reel system was proposed (Yamashita et al. 2014). In this paper, we added new data which is necessary for the current sensor applications, and we also report on many more detailed characteristics of the device. FabricationA fabrication process of the current sensor is schematically shown in Fig. 2. The detailed fabrication flow begins with a 25 μm coat of polyimide on the both sides of a 50-mmlong, 10-mm-wide and 20-μm-thick permalloy film as a magnetic core. In this work, we bonded 50-mm-long, 20-mm-wide and 25-μm-thick kapton films to the permalloy film by thermal compression bonding. Then we made through-holes 60 μm in diameter and height of 50 μm in the kapton film at 100 μm intervals along the lateral border of the permalloy film by laser drilling. An optical microscope image of the permalloy film coated with kapton films after through-holes laser drilling process is shown in Fig. 3. Then we made silver paste coil using a screen-printer (MT-320TV, Micro-tec Co., Ltd). Line/space = 50/50 μm (480 turns) that are developed in order to increase the coil turns.Abstract This paper reports a novel flexible current clamp sensor with 480 turns silver paste coil (line/ space = 50/50 μm) formed by through-holes and screenprinting technologies. Using screen-printing techniques, fine stripe patterns could be formed on a 50-mm-long and 10-mm-wide polyimide film in few seconds. Coil resistance between their contact pads is about 2.3 kΩ. When the value of a primary current was 20 A, the output voltage was 22.6 mV. Furthermore, the output voltage changed linearly with the changing of the primary current in the 0-20 A range. The sensor is developed using only coating, throughholes laser drilling, and screen-printing technologies. Therefore it can be fabricated by a reel-to-reel continuous film processing system.
