Network development alternative analysis based on Analytic Hierarchy Process

In the framework of energy transition, transmission network expansion planning process arises the need of effective and flexible tools to evaluate development options and their mutual influence, accounting for heterogenous though significant information. This paper aims to propose a new methodology developed by the Italian Transmission System Operator to identify and select the transmission network developments of higher importance for investment planning strategies. The presented approach involves the definition of alternatives by combination of network developments, by using a multi-criteria analysis involving technical and economic aspects. The method is tested on the Network Development Plan of Italian Transmission Network.
