Smart Electric Vehicle Charging System : Controlling Multiple Electrical Vehicle Chargers using OCPP to Limit Electricity Demand

2017

Master's thesis Renewable Energy ENE500 - University of Agder 2017 Peak demand is a problem when Electrical Vehicle charging is introduced in the electricity grid. Local limitations like fuses and transformer capacity can rapidly be overloaded if multiple Electrical Vehicles are charging at the same time. This can be solved by shifting these loads in time. This master’s Thesis presents a solution by using the communication protocol OCPP to restrict one or more chargers below a set demand limit. The solution is developed in cooperation with Sharebox [1] and Grønn Kontakt [2], and is in prototype phase at the end of this Master’s Thesis. Testing demonstrates that the prototype can reduce the …
