In this paper, a new method of multi-objective optimization for assessment of investment decision on reactive power support in power systems is proposed. The considered objective functions include investment cost in reactive power supports, total system loss, total voltage deviation and total system operation cost. These objectives can be incorporated in one compromise objective function using the proposed priority order multipliers, which signify the relative importance of the objectives. The method is applied to the CIGRE 32-bus test system. It has been shown that with this method, it is possible to successfully optimize four conflicting objective functions simultaneously. It is also possible to set the priority order for the each and every considered objective functions in the planning process as per the requirement of the power system operators and/or the planning authorities. The results have shown the strong reflections from the priority orders to the actual outcomes of the reactive power plan.
