Distributed Energy System Feasibility and Supportive Energy Internet Technologies

Abstract

The increasing demands of renewable energy lead to upgrading and iterating on current centralized grid system. Depends on the unique characteristics of green energies, such as photovoltaic power, wind power and so forth, the wide range of geographical allocation, power uncertainty and near to end-users has become the crucial consideration factors for next era energy system. Distributed energy system (DES) as a new emerging energy management method, it shows large numbers of similarities with renewable energy and it has been deemed as a potential reasonable way to solve the above issues. In order to illustrate whether DES have the ability to provide citizen with a sustainable, reliable and efficient grid system, this paper try to evaluate it from DES applications in different scopes and possible supportive energy internet technologies. Through discussing DES in regional and community scale, the physical limitations have been pointed out. Furthermore, micro-grid, blockchain technology and Virtual Power Plant (VPP) has been elected as potential methods to solve DES existing problems, such as data loads, inter communications between energy provider and consumer and energy trading mechanism. Since DES could not reach the optimal working status without other technologies support, how to integrate and combine different new emerging technologies into this energy system could be a further research direction. This significance of this paper is evaluating possibility of creating an autonomous, reliable, highly efficient and tradable energy system based on DES.
