With the energy paradigm shift from supply side management to demand side management, many researches have been done on demand side resource management and demand response. At the same time, Obix, BacNet-WS and OPC-UA are popularly used in buildings and industry energy management system. However, it is not easy to interchange the data and information among the systems cause a variety of protocols are used in buildings and factories. Therefore, in this paper, we are proposing an open business platform not only to integrate and manage the demand resources using various protocols and standards, but also to allow to plug-ins a new business service on top of the platform.

This paper presents an in-depth review for current status for demand-side management (DSM) investment of energy supplier and an useful prospect on the introduction of Energy Efficiency Resource Standards (EERS). According to the Article 9 of Rational Energy Utilization Act, Energy suppliers-Korea Electric Power Corporation (KEPCO), Korea Gas Corporation (KOGAS) and Korea District Heat Corporation (KDHC) prescribed by Presidential Decree-must establish and implement annual demand-side management investment plan to improve energy efficiency in production, transformation, transportation, storage and usage of corresponding energy and to reduce demand and green house gas emissions. In this paper, we examine the DSM programs of energy suppliers and the results of DSM investment in 2009, then we propose a reasonable solution for the development of DSM investment. Furthermore, in order to compare our situation, the case studies were conducted on EERS issues in England, Italy, France and U.S, such as establishing the energy saving target, selecting the target energy supplier, and penalty and incentive mechanisms. Throughout the case studies, this paper suggests the directions to the DSM investment planning of energy suppliers and the major issues to prepare EERS in Korea.

With the increasing interest of a demand side management using a Smart Grid infrastructure, the demand resources and energy usage data management becomes an important factor in energy industry. In addition, with the help of Advanced Measuring Infrastructure(AMI), energy usage data becomes a Big Data System. Therefore, it becomes difficult to store and manage the demand resources big data using a traditional relational database management system. Furthermore, not many researches have been done to analyze the big energy data collected using AMI. In this paper, we are proposing a Hadoop based Big Data system to manage the demand resources energy data and we will also show how the demand side management systems can be used to improve energy efficiency.

With the shift of the energy paradigm from supply side management to demand side management, demand resource management and demand response plays an important role in the energy industry. As a consequency, a lot of researches have been done to provide a suitable demand response system. However, most of the demand response systems are based on the propriety products that cannot be modified. In this paper, we are proposing an automated demand response system using an EnerNOC provided open source code. We implemented the demand response server (VTN) and demand response client (VEN), and validated the OpenADR2.0 compliances using the open source code. We also used an Arduino microcontoller to demonstrate the communication schemes to control various devices.

An Energy Efficiency Resource Standards (EERS) is a simple, market-based mechanism to encourage more efficient generation, transmission, and use of electricity, natural gas and heat. An EERS consists of electric, gas and/or heating energy savings targets for utilities, often with flexibility to achieve the target through a market-based trading system. In this paper, we make persons acquainted with EERS programs of foreign countries in these days. And we analyze domestic energy demand side management (DSM) programs in order to introduce an EERS program into the country successfully. Energy efficiency potential calculated in 2007 is one of the important factors for establishing an EERS program domestically. This study may provide basic data to set the amount of energy saving when an EERS program would be phased in.

Demand-side Management can be defined as'any utility activity aimed at modifying customers' use of energy to produce desired changes in the utility's load shape'. Customers benefit by being able to control energy costs and improve quality of life and become more productive. Utilities benefit from DSM's value as a resource that enhances asset utilization and reduces both fuel costs and environmental emissions. The scope of DSM includes load management through rate schedules and conservation by improving energy effciency and using electricity consumption effectively. This paper study the DSM resource evaluation and customer behavior analysis todesign the DSM Program plan in response to customer needs. We develop basic system dynamics model to analysis the customer behavior based on a survey research. The DSM Program participants in the Hi- efficiency Inverter, Electric motor and efficient lighting applicancies operating by Conservation program 2002 become the survey objects. DSM resource evaluation evaluate firstt the distribution potentialities of each machine and then forecast the degree of diffusion. We apply the system dynamic approach to simulate the dynamic DSM market situation at the domestic beginning. This model will give the energy Planner the opportunity to create different scenarios for DSM program planning. Also it will lead to increased understanding of the dynamic DSM market

This paper is developed to Energy Balance Flow show the flow of total energy resource be used nationally. The Energy Balance Flow is applicable of demand management factor through the analysis of foreign energy model of supply and demand and energy statistic data in the country. This study is based on and developed to Energy system management model is able to appraisal efficient of energy cost cutting, CO2 emission reduction and Energy saving at the national level calculated effect reached amount of primary energy to change of energy flow followed application of demand side management factor is able to appraisal quantitatively at the total energy to model of demand and supply.

본 논문은 전력시장 환경에서 수요관리 자원으로서 조광제어의 잠재량과 가치평가 방안을 제시한다. 일반적으로 수요자원의 경제성 평가를 위해 캘리포니아 테스트가 널리 사용되고 있다. 하지만 전력산업의 규제완화 및 구조개편으로 인한 새로운 시장 환경에서 캘리포니아 테스트를 적용하는데 한계가 있다. 특히 UC 테스트는 수직통합 전력회사에 적합하지만 발, 송, 배전이 분할된 전력회사에는 적합하지 않다. 따라서 본 논문에서는 전력시장 환경에서 전력판매회사 관점에서 수요관리 자원으로서 조광제어의 경제성을 평가하는 새로운 방법을 제시한다. 먼저 조광제어 자원의 잠재적 가치를 분석하고, 2006년 전력시장 데이터를 이용하여 판매회사 관점에서 조광제어의 경제성을 평가한다. 본 논문의 결과는 조광제어 자원이 전력판매회사 관점에서 비용-효과적인 수요관리 자원임을 보여 준다.

시간대별 차등요금제(Time-based Pricing)를 포함하여 전력시장에 존재하는 다양한 수요반응(Demand Response) 제도를 개발하고 이를 활성화하기 위한 정책적 수단들이 해외 선진국 전력시장을 중심으로 활발하게 진행되고 있다. 미국의 경우, 2005년 발효된 에너지법에 의하여 이러한 수요반응의 활성화가 준비되고 있으며, 이에 따라 미국의 각 주에서는 신뢰할 수 있고 활용 가능한 수요반응 서비스를 소비자에게 제공하기 위한 다각적인 노력을 시행하고 있다. 즉, 실시간 요금제도(Real-Time Pricing)와 지역별 요금제도(Locational Pricing)의 도입을 통해 시간과 공간에 따른 차등 요금제를 채택하고 있으며, 다양한 인센티브기반 수요반응(Incentive-based DR) 프로그램에 기초하여 기존의 공급자 위주의 수요관리 프로그램들이 시장 친화적 프로그램인 수요반응 프로그램으로 빠르게 변화하고 있다. 우리나라 전력시장에서도 1970년대 이후로 현재까지 다양한 수요관리사업들이 시행되어 오고 있으나, 해외 전력시장의 사례와 같이, 소비자 중심적이고 시장 친화적인 수요자원 활용으로의 전환이 체계적으로 이루어지지 않고 있는 실정이다. 따라서 본 논문에서는 수요반응자원을 전력시장에 도입했을 때 발생할 수 있는 다양한 이익(전력시장 효율 증진 효과, 공급비용 회피 효과, 현물시장 가격감소 효과 등)에 대한 정량적이고 이론적인 분석을 수행하였으며, 이를 통해 수요반응제도 도입의 사회경제적 이익을 계량화하기 위한 방법을 제시하였다.
