Power electronic applications, grid codes, power quality issues, and electricity markets for distributed generation

Abstract

This chapter discusses the need and application of power electronics in distributed generation (DG). Power electronics for DG to grid interface and power conversion have been discussed. Distributed generation (DG) gathers small-scale local technologies, controls emission, supports the grid, and saves on transmission losses and infrastructure. Power electronics are seen as enabling technologies to utilize the energy harvested from DG into usable form such as storage and feed local loads and support the local grid. Standards and codes have been reported for grid, power supply, and power quality. In grid interface network, islanding detection and anti-islanding are necessary for safety and supply continuation. Islanding types and anti-islanding methods have been classified and discussed. Role and influence of DG in electricity market is discussed.
