Abstract：Balance of load rate and risk cost are direct responses to the adaptability of substation planning results in practical applications. The mathematical model of substation planning is established, and the substation planning method considering load balancing and risk cost is put forward. Based on the risk theory, this paper establishes the cost model of equipment, substation and line, and reflects the economics and rationality of the planning result. The K-Means algorithm is used to analyze the model. The result of the case shows that the rationality of the proposed method is more reasonable than that of the traditional planning method.
