Development of community grid: review of technical issues and challenges

Abstract

The concept of a community grid is presented here. It involves the distribution grid and an increased use of renewable energy coming from distributed resources along with the consumers/prosumers engagement in energy trading mechanism. The possible operation and management with energy trading flexibility are briefly outlined. Under such scenario, the classical operation of the distribution grid is challenged by the issues brought by the large penetration level of the new energy resources. This paper presents a status review of the technical issues that may appear under the community grid scenario. Building upon those surveyed issues, this work also reviews and discusses approaches to solutions, which are required in order to make the community grid highly renewable and sustainable.
