This paper presents an optimal operating strategy of distributed generation (DG) with reliability worth evaluation of distribution systems. Using DG for peak-shaving unit could reduce the overall system operating cost, and using DG for standby power unit could reduce the customer interruption cost. If DG operating cost is less than utility power cost in peak time, DG should be running to reduce the overall system operating cost. When customer interruption cost enlarges, however, standby power strategy may be the better operating strategy than peak-shaving strategy. Selection of whether DG should be operated for peak-shaving or for standby power, needs the accurate reliability worth evaluation and the accurate power cost evaluation. Instead of using annual average reliability worth, the concept of hourly reliability worth is introduced in this paper to determine the optimal operating decision of DG. Applying suggested hourly reliability worth, the distribution companies that possess DG could set up the optimal operating strategy of DG.

In this paper, a new power control strategy for the bipolar-type low voltage direct current (LVDC) distribution system is being proposed. The dc distribution system is considered as an innovative system according to the increase of dc loads and dc output type distribution energy resources (DERs) such as photovoltaic (PV) systems and energy storage systems (ESS). Since the dc distribution system has many advantages such as feasible connection of DERs, reduction of conversion losses between dc output sources and loads, no reactive power issues, it is very suitable solution for new type buildings and residences interfaced with DERs and ESSs. In the bipolar-type, if it has each grid-interfaced converter, both sides (upper, lower-side) can be operated individually or collectively. A complementary power control strategy using two ESSs in both sides for effective and reliable operation is proposed in this paper. Detailed power control methods of the host controller and local controllers are described. To verify the performances of the proposed control strategy, simulation analysis using PSCAD/EMTDC is being performed where the results show that the proposed strategy provides efficient operations and can be applied to the bipolar-type dc distribution system.

Purpose: This study aims to measure whether the business performance of Padang restaurants in North Jakarta is primarily affected by service distribution strategy and other factors, specifically the local-based organizational culture and entrepreneurial orientation. Research design, data and methodology: This quantitative research has used Structural Model-Partial Least Square (PLS-SEM) with SMART PLS 3.0 as the analytical tool. The study's sample focus is the owner or person in charge of the Padang restaurant business in North Jakarta. Data has been collected using a questionnaire instrument with a Likert scale scale ('1-strongly disagree' to '5-strongly agree'). A total of 86 samples with a random technique were obtained from three areas in North Jakarta: Kelapa Gading, Pademangan, and Penjaringan. Results: Interestingly, this research finds that service distribution strategy does not affect business performance, either directly or indirectly. Business performance in this study is affected by entrepreneurial orientation. In additional results, the local organizational culture significantly affects the entrepreneurial orientation, but does not affect the business performance in terms of management process. Conclusions: This study provides practical implications for restaurant businesses regarding the use of local cultural concepts to consider strategies for survival in today's challenging times while continuing operations during limitations.

The study was done to provide domestic fashion multi-shops with basic Information about the distribution and the promotion strategies through an investigation the marketing strategies for domestic multi-shop dealt with imported product only. Data were collected from Interview with a buyer or a staff of marketing department of Domestic Fashion Multi-shop dealt with Imported Product only. The results were as follows： For the distribution strategies, these fashion multi-shops as chosen were all placed in department stores. Their distribution channels were diverse like road shop, shop in department store and shop under direct management of department store. In case of shop in department store, it was common that the shop paid a definite commission to the department store. But S shop was managed directly by a department store as an advanced buying system that department store bought and sold goods and held themselves responsible for overstock. For the promotion strategies, these fashion multi-shops didn't make a definite budget for advertising and publicity contrary to other one-brands. But they attached importance to visual merchandising (VMD) because they had to harmonized the concept of a shop with various brands. Also they concentrated on seasonal fashion show, management of their customers and personal sales.

The purpose of this paper is to suggest strategies for Korean companies to overcome the limitation of the international trade structure between Korea and Vietnam. This study examined foreign multinational distribution companies, Korean distribution companies and domestic distribution companies in Vietnam. A SWOT analysis conducted to propose effective strategies revealed that Saigon Mart, Vietnam's largest regional mart company, needs an O/W strategy and to capture market opportunities quickly through strategic alliances with foreign distribution companies, in order to gradually complement their core competencies internally. Lotte mart in Vietnam, one of Korea's three largest marts, needs to establish a T/S strategy in order to overcome the crisis situation in Vietnam market and succeed in business. BIG C Mart has over 40,000 diverse products needs to use a T/S strategy in order to effectively overcome the crisis situation in the Vietnamese market and to increase the possibility of business success. From the study findings and conclusions, various implications are derived. Vietnam is still very strong in socialism and regional characteristics, so it needs to build up close cooperation such as joint venture with local partners in the region and strategic alliances to increase the possibility of investment success.

This paper presents an improved grid voltage control strategy for wind farms with doubly-fed induction generators (DFIGs) connected to distribution networks based on an analysis of the operation limits of DFIG systems. A modified reactive power limit calculation method in different operation states is proposed and a reactive power control strategy during grid voltage dips/rises is further discussed. A control strategy for compensating unbalanced grid voltage, based on DFIG systems, by injecting negative sequence current into the grid through the grid side converter (GSC) is proposed. In addition, the negative current limit of the GSC is discussed. The distribution principle of the negative sequence current among the different DFIG systems in a wind farm is also introduced. The validity of the proposed voltage control strategy is demonstrated by Matlab/Simulink simulations. It is shown that the stability of a wind farm and the power grid can be improved with the proposed strategy.

Estimation of distribution algorithm (EDA) is a popular stochastic metaheuristic algorithm. EDA has been widely utilized in various optimization problems. However, it has been shown that the diversity of the population gradually decreases during the iterations, which makes EDA easily lead to premature convergence. This article introduces a hybrid estimation of distribution algorithm (EDA) with differential evolution (DE) based on self-adaptive strategy, namely HEDADE-SA. Firstly, an alternative probability model is used in sampling to improve population diversity. Secondly, the proposed algorithm is combined with DE, and a self-adaptive strategy is adopted to improve the convergence speed of the algorithm. Finally, twenty-five benchmark problems are conducted to verify the performance of HEDADE-SA. Experimental results indicate that HEDADE-SA is a feasible and effective algorithm.
