According to the analysis of coal-fired power plants, the article built the evaluation index system of coal-fired power plants energy conservation and emission reduction. Based on analytic hierarchy process (AHP), we determined the weight of each evaluation index. By using the calculation of rating scores in cleaner production, we set up a model of energy conservation and emission reduction for coal-fired power plants. On the basis of the results, the level of coal-fired power plants energy conservation and emission reduction was divided into five levels: excellent, good, medium, pass and fail. Taking a coal-power plant in Heilongjiang Province as an example, we drew a conclusion that the score of energy conservation and emission reduction in the coal-power plant was 89.52 which represents the good level. According to the evaluation result, we proposed corresponding suggestions. The results provide decision-makers with ideas and methods for energy conservation and emission reduction evaluation in the coal-fired power plant.

Facing serious environmental forms and combining structure, engineering and management emissions reduction (SEM), this paper had drew up a SEM total control evaluation index system, and built an interval optimization model of regional pollution total amount control which minimized the emission reduction costs. Through the application of model case, the interval optimal model had obtained a reasonable scheme. The minimum total costs of emission reduction was [461.51, 531.19] (108 yuan), decreasing -1.75%~11.59% comparing with the recommended scheme (522.03, 108 yuan), while the maximum emissions reduction of COD, NH3-N, SO2 and NOX were [42.58, 48.32], [6.92, 7.80], [30.72, 34.96], and [23.21, 26.78] (104 tons). The interval optimal result provides policymakers an excellent decision, expands the range of macro-decisions and controls countermeasures for pollutant total amount control program.

The Index System

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
