A Hybrid Renewable Energy Model For Medina City of Saudi Arabia Using Integer Linear Programming

Abstract

This paper describes modelling of hybrid renewable energy systems using a mathematical approach. This approach chiefly emphasizes on integratingtwo renewable energy sources viz the solar energy and wind energy. Itfocuses the need for hybrid power generationand estimationof their annual power generation.For the purpose of analysis a suitable location, Medina city in Saudi Arabia is being considered. This approach involves the concept, lossof power supply probability to minimize the initial capital investment. A Feasible solution is being arrived in presenting the integration of these renewable energy sources in a complementary way which is a technically feasible and financially viable. The conclusion of proposed method can be directly adapted, since the numbers of units are pure integer numbers. As a consequence determining the optimal energy source to be installed leads to determine the required number of units from each source. This has been modelled as an integer linear programming problem where the decision variables should be pure integer numbers.With minimal cost to get maximumeconomical power output from hybrid renewable source 5PV panel and 25 Wind Turbine can be used.
