Power Losses Contribution Tracking Using Power Flow Tracing Incidence Matrix Method Based on Renewable Energy Distributed Generator

Distribution and transmission of electric power is one of the important factors in the process of power flow from generators to customers. The energy sources used for the distribution of this power flow are also increasingly varied, one of which is renewable energy on the off-grid. Determination of the electricity contribution for each value of electrical energy between customers will be determined by first looking for the power used from each type of existing generator using the Power Flow Tracing method. By looking at the energy consumption with Incidence Matrix model, it can be determined how much the renewable energy source size by assuming that the quality of electricity provided by each generator is the same. For the simulation, the used system is IEEE 9-Bus system with given active load and reactive load, and the modified IEEE 9-Bus system with similar load for each bus represents the renewable energy source system. From the results, it is obtained that at the smaller scale, the contribution for each bus combined with renewable energy is being variative and minimize both the active and reactive power losses.
