Multi-objective Network Planning Tool for the Optimal Integration of Electric Vehicles as Responsive Demand and Dispatchable Storage

The integration of distributed energy resources (DER) into power systems presents substantial challenges to network planners. Assessing accurately the impact that installed DER will have is critical in areas such as: control of the network within statutory and operational limits; quality of supply; losses; and financial objectives. In particular, identifying the optimal placement, capacity and operational envelope for electric vehicles (EVs) when used as a responsive demand and dispatchable storage in distribution networks is desirable for network planners. The precise operation and scheduling of one or more EVs, particularly when used as a responsive demand can have a substantial impact on the network but can also offer many benefits to multiple stakeholders and this also must be accounted for in planning and operational decisions. This work investigates the effect that the inclusion of Electric Vehicles (EVs) will have on the distribution network when used as a responsive demand and dispatchable storage. The ultimate aim of this planning approach is to offer distribution network planners low cost solutions to multi-objective problems relating to EV integration.
