A multi-objective optimization model for optimizing the capacity size of the solar and wind component in a large scale PV/wind system is presented in this research. Objectives considered in the optimization include minimizing the power generation cost, maximizing the power supply reliability, and maximizing the average power fill rate. Decision variables, the number of PV arrays and wind turbines to be installed as well as the hourly load dispatches, are considered in the planning. A land budget is given to constrain the optimization. A solution algorithm is proposed to solve the proposed model and obtain exact solutions. Computational studies are performed to analyze the tradeoff among objectives in the optimization over the system's life-span. Combinations of load patterns, solar/wind resource availabilities, and penalties of power insufficiency construct different optimization scenarios. The computational results picture relationships among optimized objectives. The stability of the wind power generation contributes more than that of the solar power generation in achieving a more reliable power supply.
Power systems interconnections have many advantages not only inside a country but also for expanding international electricity trades. It is shown that grid interconnection may provide low cost, low-risk hedging opportunities against domestic uncertainty about growth in supply of and/or demand for power. This paper presents an optimization framework for (a) profit maximization in the Short-Run trading and (b) cost minimization in the Long-Run trading in power exchanges of Iran with Turkey. It is an application of a regional electricity market model to obtain an optimal power trade level between Iran and Turkey for the present as well as a 30-years sight. For both optimization models, the required objective function, parameters, variables and constraints are described. Results derived from running Short-Run model show that the export capacity of Iran is about 1000 MW, yielding a total profit of 161 M$ for one year. In addition, results derived from running Long-Run model show that, there will be greater potential for power export of Iran to Turkey which can grow 12% a year.
