Losses allocation due to penetration of DG and self-consumption operation in distribution systems. Case: PV solar energy

Abstract

This paper deals the losses allocation in distribution systems with distributed generation (DG). From an analysis based on marginalist theory for costs, losses are assigned simultaneously to generators and consumers of electricity. Taking into account, measurement samplings each 15 minutes during a typical day, it is presented an allocation proceeding of losses along the time, managing profiles of demand and generation by voltage levels. The allocation coefficients are calculated from series of power balance with shared self-consumption and power surpluses towards neighboring nodes. It was simulated through a quasi-static modeling for a network of Medium Voltage and Low Voltage, for different levels of penetration PV Solar. It is presented as an alternative for efficient allocation of losses using the Colombian case as study reference.
