Abstract
The vehicle-to-grid (V2G) concept is the basis for setting up a bi-directional electric grid interface for enabling the integration of a large number of battery vehicles (BVs) into the grid as both loads and resources that can provide electricity services for grid operations. An effective and reliable communication system is a major implementational need of the framework. The aim of this thesis is to assess whether the ZigBee wireless communication protocol can facilitate reliable data transfer under a wide range of conditions in the parking lot sub-network linking a BV to a lot coordinator.
Under the V2G framework, the BVs transmit their information to an entity that brings together a large number of BVs, the so-called Aggregator. Using the BV information and the data on the specific needs of the grid entity called the Independent System Operator/Regional Transmission Organization (ISO/RTO), the Aggregator sends control signals to the BV battery for its utilization when the BV is parked in a lot between the commute times to and from the office. Due to distance constraints, a BV cannot transmit this information directly to the Aggregator, but only to a parking lot coordinator. The coordinator relays subsequently that information to the Aggregator. Any error in the communication between the BV and the coordinator is propagated in the communication between the coordinator and the Aggregator and can cause problems in the appropriate control actions that the Aggregator makes. Such a scenario may adversely impact the grid operations. Therefore, the reliability of the communication system is critical to ensure the V2G system integration works properly.
We focus our study on the sub-network in the parking lot where BVs exchange information with a lot coordinator. Specifically, we are interested in analyzing the reliability of this communication sub-network. We do this by simulating the process and calculating its bit-error rate (BER). We compare the simulated bit-error rate with the theoretically expected value to observe whether the dense surrounding environment of a crowded parking lot is able to render data transfer unreliable.
