Testbed for Transactive Energy and its Effects on the Distribution System and Protective Devices Settings
The introduction of renewable resources is leading to significant variability in supply. This, in turn, leads to necessity of balancing supply and demand. Penetration of renewables to distribution level, including microgrids, requires new approaches to maintain distribution systems balanced and reliable. This is a complicated and challenging process that necessitates an increased level of sensors, measurements, monitoring, and protection coordination among other aspects. Integration of renewable resources with the grid is also associated with a new economic model. Move to Transactive Energy requires novel approaches in power systems design and operation, especially on a distribution level. Another important aspect of penetration of renewables is the effect on protective relays settings, especially at the distribution level.
Investigation of effects of renewable distributed generation and possible solutions require pilot projects and testbeds.
The purpose of the project was to design and implement a testbed to study the effect of the Transactive Energy concept and to assess the impact of Distributed Generation (DG) on the microgrid and protective devices settings. Physical modeling of the microgrid with DG resources was performed using xxx Laboratory at xxx. ETAP© simulation program was utilized to simulate proposed testbed and to compare simulated results with parameters of the testbed. The testbed was developed using various state-of the art laboratory modules, such as microgrid controller, Double-Fed Induction Generator (DFIG), PV systems with grid inverter, underground line module, and a number of smart meters and sensors. Monitoring and control utilized Supervisory Control and Data Acquisition System (SCADA). Data were collected and analyzed for both simulated and physical models of a microgrid with a variety of distributed renewable resources. The project resulted in a testbed to demonstrate the effects of distributed renewable resources on the balanced operation of the distribution system/microgrid as well as effect of distributed generation on protective devices settings. The project was part of senior design course with associated assessment of student outcomes and was supported by a grant from Electric Power Research Institute (EPRI).
