The widespread installation of distributed energy resources and demand side management resources into the distribution system has the potential to lead its operational parameters outside of their allowable limits. A standard strategy would be to increase the capacity of the network, however, this is costly. A cost-effective strategy could be to improve the management of such a system by improving...
This paper presents a method for optimally integrating distributed generation (DG) units and capacitors into distribution systems. The objective function of the optimization problem is minimizing real power losses. General analytical expressions are provided for determining the optimal locations and sizes of multiple DG units and capacitors. The proposed method combines the analytical expressions...
The secondary grid network allows customers in a distribution system to be supplied with minimal interruptions when outages occur. Under second contingency scenarios, where two feeders or equipment are lost, an entire grid may have to be dropped because it cannot sustain the load. This paper proposes a method to optimally partition secondary grid networks to maximize the amount of customers that can...
Power flow calculation is the most used procedure in electrical power systems. Generally, most of optimization problems in electric power systems need a steady state analysis to evaluate the objective function. Especially, those optimization problems that make use of artificial intelligence techniques, where, due to the high number of iterations, the power flow calculation has a crucial role. In these...
This paper proposes a computationally efficient methodology for the optimal location and sizing of static and switched shunt capacitors in large distribution systems. The problem is formulated as the maximization of the savings produced by the reduction in energy losses and the avoided costs due to investment deferral in the expansion of the network. The proposed method selects the nodes to be compensated,...
