How can microgrids manage EV charging?
By using BSS to manage the charging of EVs, microgrids can mitigate grid congestion issues caused by multiple EVs charging simultaneously. BSS can distribute the charging load intelligently, considering grid constraints and available capacity, to prevent overloading and ensure a reliable power supply to both EVs and other critical loads .
What is intelligent charging based on a microgrid?
The second strategy is Intelligent Charging, where vehicles charge based on the microgrid’s electrical load curve and power companies’ bidding offers. This strategy is modeled using a normal distribution function:
Is EV charging scheduling a problem in a microgrid of buildings?
In this paper, the EV charging scheduling problem in a microgrid of buildings is studied to optimize the total operation cost of the microgrid while ensuring its transmission safety. The MDP formulation is introduced to represent the uncertain supply and EV charging demand in the buildings.
What is a microgrid of buildings?
PROBLEM FORMULATION We consider a microgrid of buildings as depicted in Fig. 1. In the microgrid, each building is equipped with distributed renewable energy (DRE), hydrogen energy storage (HES) and charging piles. The building should provide charging service and keep load balance.
What is the charging scheduling problem in a microgrid system?
Different from the classical charging scheduling studies, different types of EVs, nonlinear charging characteristics of EVs, and V2G mode are considered in this work. We formulated the charging scheduling problem as CMDP, and a model-free RL framework is used to capture the uncertainty of the supply and demand sides of the microgrid system.
How is charge control implemented in a microgrid?
The charge control of each EV is implemented into two steps. Firstly, the microgrid operator controller decides a parametric charge ratio αk t as the event-based action, i.e., ak = αk ∈ [0, 1]. In this way, the total charge power for each building can be described as follows, pk = [nk . As the charge ratio αk
