Abstract
Active energy management is an effective way to realize the flexible utilization of distributed energy resources to suit the characteristics of active distribution system. Advanced active energy management strategies need to be designed to coordinate the optimization of ‘generation, network, load’. An active management model is built for the local distribution system integrated with the generation curtailment mechanism and the charging/discharging management of plug-in electric vehicles. Furthermore, different strategies based on the energy management model are presented. The model and strategies are tested and discussed in a modified distribution system, and the impacts with different load profiles are also analyzed.
Highlights
Active distribution system (ADS) is proposed to be a solution for realizing the flexible operation and maximizing the utilization of assets [1,2,3], which is driven by the low carbon target and the diversity of the distributed resources (DERs), such as distributed generation (DG), distributed storage and flexible load.Besides the opportunities, the essential challenges, for example, the energy management of ADS, have attracted the interest of researchers in recent years
This paper mainly focuses on the active management of the local distribution system, and investigates the active management strategy for the ADS from the view of achieving the maximum economic benefit for the local power company, guarantee the security itself and take the full advantage of the renewable energy and flexible charging/discharging behavior of plug-in electric vehicle (PEV)
When the PEV is plugged in, the owner has to specify the departure time and total charging energy required; ́ Private cars are mainly involved since this paper focuses on smart management of electric vehicles in the residential district
Summary
Active distribution system (ADS) is proposed to be a solution for realizing the flexible operation and maximizing the utilization of assets [1,2,3], which is driven by the low carbon target and the diversity of the distributed resources (DERs), such as distributed generation (DG), distributed storage and flexible load. PEVs can be regarded as a kind of distributed mobile storage resources, and participate in the active energy management It can be seen from the existing studies that either the generation curtailment control or PEV management is mainly used as a reserve resource to alleviate the pressure of the distribution system and guarantee security. This paper mainly focuses on the active management of the local distribution system, and investigates the active management strategy for the ADS from the view of achieving the maximum economic benefit for the local power company, guarantee the security itself and take the full advantage of the renewable energy and flexible charging/discharging behavior of PEVs.
