“…The corresponding maximum output power for each hour is obtained, shown in table II. It is observed that the more power from DG injected into the grid, the less power losses there are [11]. Thus in this paper, the PV can be controlled to inject maximum power into the grid using MPPT and the ultra-capacitor is not needed.…”

The integration of intermittent distributed energy resources (DERs) can help alleviate power loss, but also alters the load distribution and thus dynamic network reconfiguration is necessary. DERs can also work as back-up energy resources for restoring loads isolated during an outage. This paper studies the effects of DERs on the network reconfiguration problem based using the decentralized approach given in part I. Dynamic behaviors of the DERs during network restoration are studied as well.Index Terms--decentralized network reconfiguration, network restoration, photovoltaic cells, ultra-capacitor, microgrid. I. INTRODUCTIONETWORK reconfiguration for minimizing losses is one of the most important features for increasing efficiency and improving system security of an automated distribution system. Distributed generation (DG) technology brings in both challenges and opportunities on the reconfiguration issue. Proper integration of distributed energy resources (DERs) can enhance reliability, help to defer large capital investments, reduce power losses, etc. DERs are also able to restore loads isolated by system faults through the formation of a small microgrids. However, the connecting DERs to distribution systems can cause changes in voltage quality, power flows, etc. Besides, most DERs, such as wind farm and solar plant, are intermittent (stochastic) energy resources, where generation of fluctuates time-to-time due to changes in environmental conditions, so that the load distribution in the system is dynamically changing. Approaches to sizing and placement of DERs in the distribution system are discussed in [1]- [3]. The integration of DERs requires new paradigms for real-time monitoring and analysis [4]. In most scenarios, DERs are treated as negative loads, and their effects can be analyzed as time-varying loads. Opazo et al.[5]-[6] proposed an approach for reconfiguring the topology of power distribution networks taking into account time-varying load demands.In this paper, the decentralized approach presented in [7] is used to reconfigure the distribution system when DERs are

“…Analysis Malaysia lies entirely in the equatorial rainforest fully humid region [9] with an average daily solar irradiation with an approximately of 4.5 kWh/m 2 [10]. Based on Malaysia solar irradiation's latitude under equatorial climate, the annual average solar irradiation was estimated to be an approximately 1,643 kWh/m 2 [1].…”

This paper focuses on a Grid-Connected Photovoltaic (GCPV) system of amorphous Silicon (a-Si) PV module technology with total PV capacity is about 1.179 kWp. This a-Si FS GCPV system is located near to the Green Energy Research Centre (GERC) Building at Universiti Teknologi MARA (UiTM) Shah Alam, Malaysia. This a-Si FS GCPV system installation was referred to Malaysian Standard MS1837:2010 and designed based on initial data values. These days, various of the GCPV system applications in Malaysia using thin-film PV module technology was designed at stabilised data values. So, this a-Si PV system is conducted to study the PV performances and behaviors under Malaysia's perspective. After the observation period, a-Si FS GCPV system performs in good condition. The PV system generated 644.40 kWh electrical energy during the first six months of operation (June-December 2011) and the average daily energy yield of 3.03 kWh. The average monthly final yield was found to be 78.0 kWh/kWp, while the range of the initial/stabilized performance ratios between 55.8% to 78.2% and 73.0% to 102.4%.Index Terms-amorphous-Silicon (a-Si); Free-standing (FS); Grid-connected inverter; Initial system design; Photovoltaic (PV); Thin-film (TF).

“…The thermal environment influences People's outdoor thermal comfort while its use is dependent on their observation of outdoor thermal environments (Eliasson, Knez, Westerberg, Thorsson, & Lindberg, 2007;Hwang et al, 2011;Lin, 2009;Nikolopoulou, Baker, & Steemers, 2001;Thorsson, Lindqvist, & Lindqvist, 2004). Besides, outdoor thermal spaces are considerably influenced by the design of built environment (Hussin, Hamid, Zain, & Rahman, 2010;Hwang & Lin, 2007;Wong et al, 2007). Researches in the last decade have focused on determining the comfort levels in the internal environment leading to an unintentional lack of focus on thermal comfort in urban outdoor environments especially in light of the increasing UHI effect in urban areas.…”

The level of the thermal environment in urban villages open spaces plays a significant role in the personal satisfaction of a city. The different weather and climate attributes of countries as indicated by their geographical location and natural conditions directly affect people's behavior and utilization of open spaces. Hence, a naturally cognizant urban structure arrangement should give high preference to the level of comfort ramifications of urban microclimate. This paper provides an overview of urban villages in Malaysia discussing the tropical climate thermal comfort in their open areas. Malaysia still has some traditional urban villages that have not been replaced by contemporary residential projects due to the rapid modernization and urban growth within the city, keeping their design and characteristics. These characteristics affect the level of the thermal environment and the quality of life of the villages' inhabitants. This review should serve as a motive for local authorities to maintain many of the villages' existing characteristics particularly those that help mitigate the UHI effect namely the large proportion of vegetation when faced with the pressure of urban growth. The overview enhances thermal comfort's knowledge and understanding of urban open spaces in tropical climate context amongst stakeholders of urban development.
