Integrated standardization theory has been applied to work on integrated standardization for the Smart Grid Scheduling and Controlling System (SG-SCS), aiming to improve the overall quality and coordination of technical standards for dispatching and controlling in power system which help to solve practical problems. This Paper presents the definition and history of integrated standardization, and introduces the method to develop integrated standardized work for the SG-SCS which contains 4 phases: preparation phase, planning phase, standard setting or revising phase and organizing and implementing phase. The objects for integrated standardization is analyzed and determined, while the objective is addressed as well. Analysis elements related to the SG-SCS systematically and ascertain the scope of those, for target decomposition of integrated standardization. Make the complex of standards plan based on former results and determine what standards we shall set or revising. Create a detailed work plan and execute it to form a coordinated complex of technical standards. Organize the implementation of standards, with a close-looped feedback work mechanics, the overall quality and reliability of standards for SG-SCS can be ensured. By carrying out the SG-SCS integrated standardization, problems such as partly duplication or Contradiction between old standards, the overall quality of standards is promoted, which helps to the operation and control of electrical power system.

The governments of US, Japan, Europe are planning overall change of electrical power system by adapting Smart Grid as a solution of increasing demand of electricity every year. Especially, ESS have been actively studied to plan efficient use of electrical power and grid-connected. Korea government have been proceeding not only plan of renewable energy but also spread of smart grid. At the same time they have been discussing introduction of ESS which is effective solution of demand response and new growth power. In this study, according to K-ESS policy which is governmental policy of popularizing ESS. we suggest REC weighting value control among the a lot of supporting method that if renewable Genco apply ESS system they would not suffer from lose. It is meaningful because it could be referred to the way of offering governmental incentive for the purpose of decrease peak level and enhance the contribution level of peak.

 The research was conducted at the Bohol Island State University Main Campus. It aims to assess the status of the electrical power system of the university as well as determine the perceptions of the electrical experts on the satisfaction rating of the school’s electrical system. It was found out that the overall rating of the electrical system of BISU Main Campus is “fair”. This means that there are several aspects that need improvement such as the implementation of a maintenance program and the hiring of maintenance personnel. The researchers recommend that the personnel should not be the instructors themselves but designated electrical technologists must be hired. Furthermore, there should be a periodic inspection so that defects may be detected and given remedies the earliest time possible to avoid accidents. There should also be fund allotment that should be imposed for the maintenance and personnel. Furthermore, the university must purchase more electrical supplies, tools and equipment solely for electrical maintenance. There must also be a separate maintenance shop for maintenance purpose only. An alternative electrical power source should be employed by the university such as the solar power. Because of the very high and expensive electrical energy consumption, there is a need to use a more efficient alternative source and that is the solar power. Keywords - electrical power system, electrical energy consumption

: This paper presents electrical power system comprises many complex and interrelating elements that are susceptible to the disturbance or electrical fault. The faults in electrical power system transmission line (TL) are detected and classified. But, the existing techniques like artificial neural network (ANN) failed to improve the Fault Detection (FD) performance during transmission and distribution. In order to reduce the power loss rate (PLR), Daubechies Wavelet Transform based Gradient Ascent Deep Neural Learning (DWT-GADNL) Technique is introduced for FDin electrical power sub-station. DWT-GADNL Technique comprises three step, normalization, feature extraction and FD through optimization. Initially sample power TL signal is taken. After that in first step, min-max normalization process is carried out to estimate the various rated values of transmission lines. Then in second step, Daubechies Wavelet Transform (DWT) is employed for decomposition of normalized TLsignal to different components for feature extraction with higher accuracy. Finally in third step, Gradient Ascent Deep Neural Learning is an optimization process for detecting the local maximum (i.e., fault) from the extracted values with help of error function and weight value. When maximum error with low weight value is identified, the fault is detected with lesser time consumption. DWT-GADNL Technique is measured with PLR, feature extraction accuracy (FEA), and fault detection time (FDT). The simulation result shows that DWT-GADNL Technique is able to improve the performance of FEA and reduces FDT and PLR during the transmission and distribution when compared to state-of-the-art works.

Optical Current Transformers (OCTs) and Optical Voltage Transformers (OVTs) are an alternative to the conventional transformers for protection and metering purposes with a much smaller footprint and weight. Their advantages were widely discussed in scientific and technical literature and commercial applications based on the well-known Faraday and Pockels effect. However, the literature is still scarce in studies evaluating the use of optical transformers for power quality purposes, an important issue of power system designed to analyze the various phenomena that cause power quality disturbances. In this paper, we constructed a temperature-independent prototype of an optical voltage transformer based on fiber Bragg grating (FBG) and piezoelectric ceramics (PZT), adequate to be used in field surveys at 13.8 kV distribution lines. The OVT was tested under several disturbances defined in IEEE standards that can occur in the electrical power system, especially short-duration voltage variations such as SAG, SWELL, and INTERRUPTION. The results demonstrated that the proposed OVT presents a dynamic response capable of satisfactorily measuring such disturbances and that it can be used as a power quality monitor for a 13.8 kV distribution system. Test on the proposed system concluded that it was capable to reproduce up to the 41st harmonic without significative distortion and impulsive surges up to 2.5 kHz. As an advantage, when compared with conventional systems to monitor power quality, the prototype can be remote-monitored, and therefore, be installed at strategic locations on distribution lines to be monitored kilometers away, without the need to be electrically powered.

Power Transfer Distribution Factors

Abstract This article presents a comparison between two different methods to perform model reduction of an Electrical Power System (EPS). The first is the well-known Kron Reduction Method (KRM) that is used to remove the interior nodes (also known as internal, passive, or load nodes) of an EPS. This method computes the Schur complement of the primitive admittance matrix of an EPS to obtain a reduced model that preserves the information of the system as seen from to the generation nodes. Since the primitive admittance matrix is equivalent to the Laplacian of a graph that represents the interconnections between the nodes of an EPS, this procedure is also significant from the perspective of graph theory. On the other hand, the second procedure based on Power Transfer Distribution Factors (PTDF) uses approximations of DC power flows to define regions to be reduced within the system. In this study, both techniques were applied to obtain reduced-order models of two test beds: a 14-node IEEE system and the Colombian power system (1116 buses), in order to test scalability. In analyzing the reduction of the test beds, the characteristics of each method were classified and compiled in order to know its advantages depending on the type of application. Finally, it was found that the PTDF technique is more robust in terms of the definition of power transfer in congestion zones, while the KRM method may be more accurate.
