Optimal Power Flow in Electrical Microgrids

Algorithm Based on the Gradient Method

In order to analyze electrical microgrids by OPF, a mathematical algorithm is proposed based on the gradient method, based upon the study developed in [10]. Figure 3 shows the proposed flowchart of an OPF solved by the gradient method.

The mathematical algorithm is based on partial derivatives and has the property to be modified to analyze any structure in the microgrid (isolated or interconnected with the grid).

In Section 3.1 the general way of formulating an OPF is shown. Afterwards, in Section 3.2 the specific methodology proposed for the formulation and solution of an OPF is explained, which is based on the gradient method with the purpose of improving the voltage profiles and reducing active power losses in electrical microgrids.

More of an FYI, but SimPowerSystems implements this same type of power flow analysis:
