This paper proposes an electric vehicle (EV) charge-discharge management framework for the effective utilization of photovoltaic (PV) output through coordination based on information exchange between home energy system (HEMS) and grid (GEMS). In our proposed framework, HEMS determines EV charge discharge plan reducing residential operation cost PV curtailment without disturbing usage driving, basis voltage constraint in provided by GEMS forecasted power profiles. Then, controls according to...
Distributed generators (DGs) such as fuel cells, solar wind mills and micro gas turbines, etc. are going to be installed on the demand side of power systems. Such distributed can reduce distribution loss if they placed appropriately in system. In this paper, a tabu search application for finding optimal allocation DGs from viewpoint minimization is illustrated. other words, authors discuss about an implementation method find how much reduced optimally allocated at Namely, locations discrete...
In this paper, we consider the impact of cyber attacks on voltage regulation in distribution systems when a number photovoltaic (PV) are connected. We employ centralized control scheme that utilizes measurements from sectionizing switches equipped with sensors. It is demonstrated if falsified by an attacker, violation can occur system. However, equipping detection algorithm, verify damage be limited especially attacked sensors small through theoretical analysis and simulation case studies....
Atopic dermatitis (AD) is prone to exacerbations in response various triggering factors and flare-ups after remission. We searched for molecules associated with relapse/exacerbation of AD among altered gene expression the skin patients AD. Microarray analyses were performed on lesional non-lesional adolescent or adult recalcitrant healthy controls. Five chaperones involved intracellular stress responses, namely heat shock protein family A (Hsp70) member 9 (HSPA9), 90 beta 1 (HSP90B1),...
This paper describes a method of solving large scale long-term thermal generating unit maintenance scheduling problem.

The keeps advantages individual algorithms shows reasonable combination local global searches. takes class several consecutive years into consideration. Several real-scale numerical examples demonstrate effectiveness proposed method.
This paper proposes an electric vehicle (EV) charging management scheme for effective utilization of photovoltaic (PV) power based on auction mechanism. The proposed coordinates amount self-consumption PV output by shifting the period customers' EVs, and it reduces curtailment caused voltage rise in low-voltage distribution systems (LVDSs). mechanism is introduced order to assure both equity benefit each customer autonomy that enables customers voluntarily participate EV scheme. authors...
Wind power is one of the most attractive forms electricity from viewpoints cost efficiency and environmental protection. However, instability wind has a serious impact on grid system. Reliable forecasting will help to utilize storage systems backup generators effectively for mitigating instability.

Battery energy storage systems (BESSs) have attracted much attention as a key device for realizing the installation of photovoltaic plants (PVPs) in distribution networks. To improve cost-effectiveness BESSs, multipurpose utilization is required. In addition, BESSs network are generally used over decade or more, and role size may change according to network's condition, such PVP penetration level. Consequently, an ad hoc BESS increase excess capacity, which detrimental cost-effectiveness....
Wind power is an unstable source, as its output fluctuates drastically according to the weather. Such instability can cause sudden large-scale changes in output, called ramp events; frequency of such events relatively low throughout year but they could negatively affect supply-demand balance a system.
