PROPOSING AN ECONOMIC PLANNING MODEL TO DETERMINE OPTIMAL CAPACITY OF A FLEXIBLE WIND POWER PLANT

Abstract

It is difficult but essential to decide on the cost planning and borrowing method to implement large-scale projects under uncertain time conditions. Considering the unique design of each power plant and the climatic conditions affecting its design and establishment, conducting any research for the design and implementation of special projects such as wind power plants (WPPs) requires the utiliza-tion of uncertain models for planning in order to provide appropriate financial resources and manage the use of WPPs. Tradtional design of power systems is in such a way that offer a flexible context where demand is fulfilled by mass generation. Besides, flexibility required for maintaining load-generation balance is increased by the incorporation of uncertain and variable renewable generation sources, like wind. This manuscript is an attempt to determine the sizing of the WPP capacity along with the amount of storage capacity that can provide the possibility profit for the investor, consider-ing the uncertainties and challenges available in this regard. Thus, it is essential to specify in the planning horizon the amount of load needed by the grid, the wind level of the geographical area, the wind farm’s output power and the interest rate, all of which have major uncertainties. This is possible by presenting a mixed integer model and considering the behavior and characteristics of the storage WPP and the challenges of grid flexibility. To develop this hybrid model, possibilistic programming will be used for optimization.
