Optimal allocation of biomass distributed generation in distribution systems using equilibrium algorithm

Abstract

The majority of power utilities have targeted pretentious clean and efficient energy plans. These plans are accompanied in driving down the cost of biomass distributed generation units (BDGs). This paper proposes an optimal allocation procedure of BDGs to enhance the performance of the distribution systems and to reduce the related environmental emissions. The proposed procedure aims to maximize the power utilities' benefits in terms of power loss reduction, energy sales excess, and pollutant emission reduction. It also takes into consideration the minimization of the annual operational and maintenance costs of the BDGs. The load growth with several loading levels over the BDGs planning period is presented. For achieving this target, an adaptive equilibrium optimizer (EO) technique is developed which is characterized by simple structure and dynamic control parameters. The proposed procedure is applied to IEEE 33-bus and practical large-scale 141-bus system of AES-Venezuela in the metropolitan area of Caracas. The simulation results declare the effectiveness and capability of the employed EO technique in achieving great benefits in terms of energy sales and environmental emissions with a high improvement of the voltage profile and minimizing power losses. In addition, a comparative and statistical analysis is executed with several recent techniques to show the superior capability of the proposed procedure using the EO technique.
