The optimal planning of substation location is very significant for the construction of a reliable and reasonable power system, for this purpose, the comprehensive evaluation index system and the evaluation method are researched. Firstly, for the optimal layout of substation location an evaluation index system, which covers four aspects, i.e., security, economy, environment and operation, is established. Then, with a comprehensive consideration of the subjective weights and the objective weights, optimal combination weighting based on moment estimation theory is used to determine the optimal combination weight of each index. On this basis, an improved grey relational analysis method is proposed through a combination of grey relational analysis and cosine sorting method, to determine the optimal site selection more accurately and reasonably. Finally, using the proposed evaluation index system and evaluation method, the location of the newly added substation location in Phnom Penh power system is researched and the conclusion that Plan I should be taken as the location for the newly added substation is attained. The effectiveness and feasibility of the proposed evaluation index system and evaluation method are verified by the attained conclusion. Moreover, it shows that it has good application value for the optimization of substation location planning.
