Electricity is basic need for country development. But at the present time proper planning and policy is require at high pace for power generation network extension due to the increasing population growth rate. Present study aimed to analyze the present and future demand for electricity at household level in Province of Balochistan of Pakistan via simulation modeling. Data of year 2004-2005 was used as baseline data for electricity consumption to predict future demand of electricity at both rural and urban domestic level up to subsequent 30 years, with help of LEAP software. Basically three scenarios were created to run software. One scenario was Business-As-Usual and other two were green scenarios i.e., solar and wind energy scenarios. Results predicted that by using alternative energy sources, demand for electricity will be fulfill and will also reduce burden on non-renewable energy sources due to the greater potential for solar and wind energy present in Balochistan.

Currently, the domestic electricity rates for houses are charged by applying a progressive level according to monthly electricity usage. Electricity rates rise sharply wWhen the amount of electricity used is large, electricity rates rise sharply. The standardized electricity rate progressive system has limitations in that it lacks consideration of the consumers' power usage patterns and limits consumers' their options. Accordingly, the Ministry of Trade, Industry and Energy and the Korea Electric Power Corporation have been demonstrating the basis of a rate system for housing, which is a method of charging electricity according to the amount of electricity used by season and time. In this paper, 10 electricity usage patterns were derived through from AMI data analysis for 5 five years of 362 apartment complexes located in metropolitan cities. The patterns were, and then applied to the existing domestic electricity rate and time-by-time rates applied to demonstrations, and by time-by-time rates in the US and Australia. The effect of the optional rate by pattern was compared and analyzed. As a result, it was confirmed that benefits occurred in five5 patterns compared to existing rate plans, and the electricity rates increased in 5 five patterns, and t. This phenomenon shows the same phenomenon withis the same as the overseas rates, including domestic rates being demonstrated.

For the introduction of the electricity of the special design and supervision system to Protect the faulty-workmanship of the electricity equipment and to reserve the electricity safety, last 1995 "Electricity Technology Management Act" were carried out enactment. March 2002, we introduced the pre-Qualification system that is selected the competent company about the electricity design and supervision service over so much capacity which is ordered by the Public institution such as the nation, local autonomous entity, government investment institute and so on. December 2005, the electricity equipment over so much capacity was taken the housing construction plan's approval by the housing act in case, the municipal or district governor with the authority to approve who selected the electricity supervision company according to the pre-Qualification system. Due to the introduction of the system, we could expect the rights and interests increase of the consumer by eradicating dumping of the close relationship between supervision company and the builder, reduction and concurrent position of the supervisor, according to confirm the quality of the electricity equipment and electricity safety. In spite of introducing of the system, the problems occured as reducing the electricity designer's task range compared with different field, modifing the supervisor's rank system rationally, because of researching about the electricity design and supervision technique lacks. Also, KEEA(Korea Electric Engineers Association) manage the caller of the electricity design and supervisor(company or people), but the problems occured as opening to the public about the curler management, introducing automatic bidding system and We need the solution plan about this. Consequently, we consider the present situation of the domestic and outside and problem about the electricity design and supervision system in this paper, try to present rational operation plan through this.

This study investigated (1) consumer perception about the level of electricity price, (2) the amount of household electricity consumption, and (3) consumer perception on electricity pricing system reform. For data collection, a national wide survey was conducted between November 22 and December 15, 2006. Excluding 233 cases, because of incomplete responses, data from 1767 households were analyzed. The major findings were as follows; More than 50% of the respondents consumed between 100-300kWh of electricity per month. Household size and income were significantly associated with electricity consumption. Approximately 50% of respondents perceived that electricity was being overcharged. Approximately 50% of the respondents positively evaluated the effects of the graduation pricing system. Households consuming more than 300kWh of electricity per month preferred a flat unit price. Based on these results, we suggest the implications to reforming the electricity pricing system.

According to the Renewable Energy 3020 Implementation Plan announced in 2017 by the South Korean government, the electricity share of renewable energy will be expanded to 20% of the total electricity generation by 2030. Given the intermittency of electricity generation from renewable energy, realization of such a plan presents challenges to managing South Korea's isolated national electric grid and implies potentially large excess electricity generation in certain situations. The purpose of this study is: 1) to develop a model to accurately simulate the effects of excess electricity generation from renewables which would arise during the transition, and 2) to propose strategies to manage excess electricity generation through effective utilization of domestic electricity generating capabilities. Our results show that in periods of greater PV and wind power, namely the spring and fall seasons, the frequency of excess electricity generation increases, while electricity demand decreases. This being the case, flexible operation of coal and nuclear power plants along with LNG and pumped-storage hydroelectricity can be used to counterbalance the excess electricity generation from renewables. In addition, nuclear energy plays an important role in reducing CO₂ emissions and electricity costs unlike the fossil fuel-based generation sources outlined in the 8th Basic Plan.

With the wide application of intelligent household appliances, the optimization of electricity behavior has become an important component of home-based intelligent electricity. In this study, a multi-objective optimization model in an intelligent electricity environment is proposed based on economy and comfort. Firstly, the domestic consumer's load characteristics are analyzed, and the operating constraints of interruptible and transferable electrical appliances are defined. Then, constraints such as household electrical load, electricity habits, the correlation minimization electricity expenditure model of household appliances, and the comfort model of electricity use are integrated into multi-objective optimization. Finally, a continuous search multi-objective particle swarm algorithm is proposed to solve the optimization problem. The analysis of the corresponding example shows that the multi-objective optimization model can effectively reduce electricity costs and improve electricity use comfort.

This study analyzed the influence of domestic and Chinese factors on fine dust(PM10 & PM2.5) in Korea by using the panel quantile regression. Daily analysis was conducted for 11 regions in Korea. For domestic factors, electricity demand and traffic volume, and for Chinese factors, interaction term of Chinese three cities' fine dust and the domestic west wind are used. As a result, the influence of domestic factors was different when the domestic fine dust concentration was high and low. When the fine dust concentration was low, electricity demand had a positive effect only on PM2.5, and didn't affect PM10 in the national analysis. In regional analysis, the amount of electricity demand had a significant effect on fine dust and ultrafine dust only in the capital area and Chungcheong. Electricity demand was found to significantly increase both PM2.5 and PM10 when it was high. On the other hand, it was confirmed that the Chinese factor always had a significant effect regardless of the concentration of PM10 and PM2.5. Therefore, in order to solve the problem of high concentration of fine dust, in addition to international cooperation, the reduction of PM2.5 generated by domestic thermal power generation should also be strengthened compared to the present.
