Establishing an accurate load model is a critical problem in power system modeling. That has significant meaning in power system digital simulation and dynamic security analysis. The synthesis load model (SLM) considers the impact of power distribution network and compensation capacitor, while randomness of power load is more precisely described by traction power system load model (TPSLM). On the basis of these two load models, a load modeling method that combines synthesis load with traction power load is proposed in this paper. This method uses analytic hierarchy process (AHP) to interact with two load models. Weight coefficients of two models can be calculated after formulating criteria and judgment matrixes and then establishing a synthesis model by weight coefficients. The effectiveness of the proposed method was examined through simulation. The results show that accurate load modeling based on AHP can effectively improve the accuracy of load model and prove the validity of this method.

Because of the frequent occurrence of injury accident in the sports curriculum, the security of physical education cannot be ignored. So, this paper analyzes the factors of injury accident in physical education teaching process and proposes prevention measures. The establishment of security system in physical education is an urgent problem. This paper studies the causes and countermeasures of sports injury accidents based on two methods: causality diagram and analytic hierarchy process. The first section introduces the principles of causality diagram and hierarchical analysis in detail. The second part of the article establishes mathematical model of the analysis method. The part three of the text investigates and analyzes the accident status and prevention measures of 100 primary schools and universities in Heilongjiang province in the form of literature researches and questionnaires. It also proposes weight coefficients and causality diagrams of Sports Injury Accidents using causal analysis theory. It converts causal diagram into a hierarchical model using the analytic hierarchy process AHP.

Improved Analytic Hierarchy Process

Reasonable black-start scheme is of great significance to power system restoration. The entropy method and improved analytic hierarchy process algorithm are applied in evaluation indexes determination. Compared to the traditional algorithm, it takes into account the objectivity of reality and the subjectivity of human experience and adjusts both relative importance by a impact factor. It dose.t need the optimization calculations. At the same time, the fuzzy consistent matrix is applied to improve the traditional analytic hierarchy process, avoiding the consistence problems. Finally, compare the pros and cons of each program by calculating the comprehensive evaluation index to achieve the program’s full sort. The calculation process is simple, the efficiency is obviously improved and the availability of the method is validated through an example.

The scheduling of a hydrothermal power system needs to take into account multiple economic, social and environmental criteria, such as power production, flood protection and control, water supply for agricultural, industrial and domestic uses, navigation, water quality control, ecological environment protection, fishery, recreation, and pollutant emission control. In addition, determination of the scheduling must involve the participation of various stakeholders. Hence, this paper proposes a framework for multi-criteria evaluation of the scheduling of a hydrothermal power system based on group decision making using analytic hierarchy process (AHP). The AHP is used to select a balanced scheduling scheme out of a number of alternatives through performing pairwise comparisons according to judgments of the decision group members.
