The purpose of this paper is to seek out the problems influencing on the operation of Institution Evaluation(IE) in Korea and suggest a better way for the evaluation based on the findings, expecially focusing on Government Research Institute(GRIs) in the field of Science and Technology. Unlike previous studies on IE of GRIs, this research is more oriented toward actual practices than design and theories of IE. Three categories are 1) purely system aspect, 2) system-operation aspect, and 3) environmental aspect. These three categories are classified into eight sub-categories: 1) the legal support and the legally enforceable provision, 2) the target area of evaluation, 3) the means and process of evaluation, 4) the criteria and indices for evaluation, 5) the expertise of evaluators, 6) the use of evaluation findings, 7) GRIs' support for IE, and 8) public support for IE. Summing up the findings of this study, the main factors that hamper the successful operation of the existing IE of GRIs in the field of Science and Technology was illuminated and the better way for the operation of IE was suggested.

In this paper, for minimizing the real-time operating load losses of the power transformer, a SCADA optimum operating system was developed, and the economic analyses on the test operation were performed. Transformer loss DB which reflects the economic integration operation criteria was constructed by referring the transformer manufacturer's loss data(iron loss, copper loss). Based on the loss DB, each substation transformer real-time loss was calculated according to the size of the transformer loads, and if integration or separation transformer operating conditions minimizing the loss are met, then a window pops-up and the dispatcher performs the substation equipments operation according to the procedure provided by this system. With the existing SCADA main program, the relation database of the substation facilities and integration/separation operation algorithm were developed and applied to Auto MTR Processor and pconn Processor Task module. Seven stations test data for seven months were analyzed for the economic analyses, and the results showed that Cost-Benefit ratio was 2.64, and IRR(Internal Rate of Return), 36%, which asserted the economic justification of the proposed system.

By development of renewable energy and more efficient facilities in an increasingly deregulated electricity market, the operation cost of distributed generation (DG) is becoming more competitive. International environmental regulations of the leaking carbon become effective to reinforce global efforts for a low-carbon paradigm. Through increased DG, operators of DG are able to supply electric power to customers who are connected directly to DG as well as loads that are connected to entire network. In this situation, a community energy system (CES) with DGs is a new participant in the energy market. DG's purchase price from the market is different from the DG's sales price to the market due to transmission service charges and other costs. Therefore, CES who owns DGs has to control the produced electric power per hourly period in order to maximize profit. Considering the international environment regulations, CE will be an important element to decide the marginal cost of generators as well as the classified fuel unit cost and unit's efficiency. This paper introduces the optimal operation of CES's DG connected to the distribution network considering CE. The purpose of optimization is to maximize the profit of CES. A Particle Swarm Optimization (PSO) will be used to solve this complicated problem. The optimal operation of DG represented in this paper would guide CES and system operators in determining the decision making criteria.
