The case study involves three charging parks with various sizes of coupled storage systems in a test grid in order to apply the developed method. By operating these storage systems using the coordinated control strategy, the maximum peak load can be reduced by 44.9%.
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
Using the coordinated control strategy, the peak load can be reduced by 44.9%. Storage systems are evaluated using KPIs along with its impacts on the grid. Both global climate change and the decreasing cost of lithium-ion batteries are enablers of electric vehicles as an alternative form of transportation in the private sector.
As mentioned in Section 4, the peak load in the test distribution grid without EVs is 11.1 MW and the maximum peak load reduction of 44.9% (dark blue area in Fig. 8) at the PCC compared to a scenario without EVs occurs at the largest BESS capacity (2 MWh each) and the smallest EV-share (4%).
However, a high electric vehicle penetration in urban distribution grids leads to challenges, such as line over loading for the grid operator. In such a case installation of grid integrated storage systems represent an alternative to conventional grid reinforcement.
It is shown that the coordinated control strategy can significantly reduce the peak load on the PCC. This opens up new possibilities, allowing the grid operator to avoid grid reinforcement without influencing EV owners with reduced charging power or V2G strategies.
