This paper proposed a new diffusion model considering DSM rebate program's support conditions. The proposed method used some aspects of the rebate program such as support qualifications, annual support volume, and support level per appliance as following : The support qualifications were limited as the consumer which can get the rebate program's benefit, the annual support volume was constrained as the fixing budget and the support level per appliance was considered by high-efficient appliance actuality price. This paper also proposed a new method that used neural network as its parameter estimation moth[,4 for the diffusion model. The diffusion model and its parameter estimation method are expected to be able to analyze the diffusion characteristics of high-efficient appliance through the rebate program and the effects of rebate program's support conditions. Also, these will be able to evaluate the impacts and to analyze the cost-effectiveness of Energy Efficiency Demand-Side Management(EEDSM) resources. The case study is performed on the high-efficient lighting appliance rebate program of Korea by using the suggested diffusion model and estimation method and thus verified its validity.

In this paper, a modified diffusion model integrated with the effects of rebate programs is developed. The greater part of motors is included to various systems such as pump systems, fan systems, ventilation systems, motor itself, and so on. Hence, the existing rebate program is not suitable for these systems and a generalized rebate model for these systems is necessary. In the pre-study, a new diffusion model for motor rebate Program was proposed and the adequacy of this model was evaluated in the case of Korea. This paper shows that the motor rebate model could be applied to the case of pumps.

This paper analyzes the customer behavior on high efficiency inverter program in terms of rebate levels. The importance of high efficiency DSM programs has been more and more increased after deregulation. Especially, the inverter program is one of the most high efficiency DSM programs, so this paper presents proper rebate levels in terms of both participants and non-participants to promote diffusion of the inverters.

This paper presents the evaluation procedures and the estimation method for the estimation of optimal rebate level for EE(Energy Efficiency) programs. The penetration amount of each appliance is estimated by applying price function to preferred diffusion model resulted from model compatibility test. To estimate the optimal rebate level, two objective functions which express the maximum energy saving and operation benefit are introduced and by multi-objective function which can simultaneously consider two objective functions the optimal rebate level of each appliance is estimated. And then, using the decided rebate level and each penetration amount, the priority order for reasonable investment of each high-efficiency appliance is estimated compared to the results of conventional method. Finally, using a benefit/cost analysis based on California standard practice manual, the economic analysis is implemented for the four perspectives such as participant, ratepayer impact measure, program administrator cost and total resource cost.

There are some rebate programs for energy efficient appliances, which are lightings, vending machines, ASDs, motors, transformers, pumps, to reduce national energy consumption in Korea. In existing studies, some diffusion models have been applied to the rebate program case. But those studies could not consider various cases in duration, amounts, whether or not, of rebates. Hence, new diffusion models considering the time-variant diffusion status are proposed for high-efficient appliance rebate programs in this paper. The case study shows the application of these model into some high-efficient appliances.

In this paper, the proper rebate level can be decided in programs of energy savings by solving an optimization problem with an objective function, which satisfies a maximum value of total energy savings. And then, each prevalence amount is estimated by using virtual Bass model which is a function of rebate level, instead of the conventional Bass model. Finally, by cost/benefit analysis of the estimated prevalence amounts, the priority order is obtained for the investment of each program. The priority order obtained in this way may result the improvement of investment efficiency for DSM(Demand-Side Management) programs and the reasonable plan decision for supply and demand in power system.

본 연구에서는 DSM 프로그램 개발에 있어 가장 일반적인 수행수단으로 활용되고 있는 리베이트의 적정수준 결정을 위한 방법과 절차를 제시하였다. DSM 기술의 비용효과 분석에 있어서는 전력회사의 회피비용과 기술비용을 각각 편익과 비용지표로 산정하였으며, 이를 토대로 RIM 및 TRC 지표에 의해 상이한 리베이트 수준에서의 시뮬레이션을 반복적으로 시행하였다. 적용 대상 프로그램으로는 현재 국내에서 시행되고 있는 고효율 조명프로그램의 전자식 안정기를 택하였다.

The electricity demand in Korea has rapidly increased along with a steady economic growth since 1970s. Therefore Korea has positively propelled not only SSM(Supply-Side Management) but also DSM(Demand-Side Management) activities to reduce investment cost of generating units and to save supply costs of electricity through the enhancement of whole national energy utilization efficiency. However study for rebate, which have influence on success or failure on DSM program, is not sufficient. This paper executed to modeling mathematically an amount of potential participants considering rebates, which have influence on penetration amounts for DSM program using by 'A Survey of End-User for Energy Efficiency Demand Side Management Programs'.

한국의 전력 산업은 현재 개발도상국들의 급속한 경제성장에 의해 연료가격이 상승하고 NIMBY현상으로 인해 발전설비의 확장에 필요한 입지선정에 어려움을 겪고 있다. 이러한 현상은 설비의 확장을 통한 공급측 수요관리(Supply-Side Management)에서 벗어나 전력사용의 효율성을 향상시킴으로써 안정적인 전력을 공급하는 수요측 관리(Demand-Side Management)의 중요성을 점차 크게 하고 있다. 수요측관리는 지원금을 이용하여 전력수요를 조절하고 있으며, 수요관리의 중요성이 커짐에 따라 지원금 규모는 점점 커지고 있다. 하지만 현재 지원금 산정에 대한 구체적인 연구가 진행되고 있지 않은 실정이므로 이에 대한 연구를 통해 더욱 효율적인 지원금 산정을 통한 수요관리 효과를 극대화 할 필요가 있다. 본 논문에서는 07년도에 지원금변화에 대한 잠재참여자의 선호도를 조사한 "지원금에 대한 수용가 반응도 조사"를 이용하여, 지원금 변화에 따른 수요관리 프로그램의 잠재참여자의 참여도를 수식화 함으로써 지원금 변화에 대한 수요관리 프로그램의 영향도를 분석할 수 있게 하는데 목적을 두고 있다.

DSM activities have grown and matured over several years in Korea. KEPCO is currently offering some DSM programs in industrial, commercial, and residential customers such as rebate program in purchasing efficient measures. The systematic evaluation process of energy savings and peak reduction will be very important for deciding on the optimal investment of DSM activities in utilities in the future. In general, the estimation process of the potential savings of DSM activities include the determination of baseline electricity consumption, the instantaneous technical potential (ITP), the phased technical potential (PTP), the economic potential (EP), and the achievable potential (AP). The purpose of this article is to provide evaluation process of those DSM potential savings based on bottom-up approach and applicate to residential sector in Korea. In case study, ITP, EP are estimated to be respectively 21.5%, 5.7% of total energy consumption, and 4.1%, 2.5% of peak load in 2010.
