Analysis of the Criterion for Connecting New Source to Distribution Grid According to the Steady State Evaluation
Authors: , , , ,
Abstract: Nowadays power systems, especially the electrical distribution grids are accommodating different renewable technologies resulting into increasing complexities and instabilities. The dynamic growth towards to renewable energy is measured by also considering the impact of distributed generation on the grids. Distributed generation is the electricity production from small sources and is located close to the final consumer. The purpose of distributed generation deployment is to improve the energy independence and if appropriate technology is used, distributed generation can participate on grid control actions. Besides the declared advantages in favor of distributed generation, the responsible bodies have to take measures to ensure the advantages will become visible. The base of safe and sustainable distributed generation deployment is the planning and setting the national targets based on the technical assessment. With planning national aims for renewable energy sources is necessary to regard various technical restrictions. One of the basic criteria for connecting new source to distribution grids is to adhere the voltage limits in networks. In efforts to estimate the impact of operation of a new source on voltage, distribution network operators define a criterion for the maximum permitted voltage change in steady state operation. This article deals with analysis of a voltage criterion and compares it with steady state calculation using the simulation model of 22kV feeder.
