Optimal sizing of combined heat and power generation units using of MPSO in the Besat Industrial Zone

The paper deals with the dynamic determination of the optimal sizing of CHP generation units using of MPSO. The optimal size of the CHP generation units as distributed generation resources has been performed for reliability improvement, loss reduction, electrical and heating energy supply in Besat Industrial Zone in Tabriz, Iran. The objective function of the optimization problem has been defined in relation to the profit gained via the installation of the CHP to the costs of this installation. Proposed function includes the costs of investment, operation, repair and maintenance of CHP units. The principles process includes the power flow and the generation limitations of the CHP units. In order to define the problem as a dynamic programming for the planned years, the interest rate and the annual inflation have been considered in the calculation of the electrical and heating energy costs. The findings of the simulation indicate positive effects of CHP units on electricity grid of Besat Industrial Zone.
