In this paper, by using a new analytical method based on iteration and simultaneous maximizing net profit value in investment circulation for wind turbine developers at the presence of pumped-hydroelectricity energy storages (PHESS) in power systems, improvement and social welfare of present partners in energy and reserve markets in an annual time interval, is presented. Obtained results of the proposed method are tested on a standard 14-bus IEEE system. And by using analysis and evaluation of the presented method it is determined that due to proving high flexibility in operation planning of system under the conditions of pool-based market during the annual horizon, maximizing investment profit of these resources and other partners under the market conditions is achieved.
