Due to ever increasing electricity demand, aging infrastructure, and financial constraints, future power systems need innovative solutions to meet the demand requirements at a rational cost. The objective of this dissertation is to assess the load flexibility potential benefits of utilization improvement and better life management for major assets of high voltage grid. The objective is further divided into tasks in order to distinguish the benefits among operational stages, planning phases, and various components. Primary substation transformers have been given special attention due to their vital position in the distribution system and their high individual component cost. At first, mathematical models are proposed for the intended targets. Subsequently, simulation results are obtained for typical Finnish systems. The results indicate that the load flexibility offers significant better planning and life management opportunities for transformers. Furthermore, optimal decisions of flexible load activation are essential in order to obtain the intended benefits at a minimal expense. Power system utilities can use the proposed models of this dissertation for making decisions before deploying load flexibility schemes. These schemes will be helpful in delaying or eliminating the capacity investments.
