Control of hyprid PV plants in the future power systems
November 4, 2022
Location: HEC-450 at 10am.
With the increasing penetration of renewable generation and storage systems, new control methods have to provide a seamless transition from today’s grid to the future renewable-dominated grid at different time scales. Using a hybrid PV plant as an example, this talk will discuss how PV and storage sys-tems can provide similar functionalities as a conventional generation plant in the energy market and sup-port grid transient stability.
- First, a forecasting-based bidding algorithm that enables the hybrid PV plant to join the market will be introduced. Each hybrid plant bids into the day-ahead market based on the forecasted PV generation and a particular battery operation strategy. The objective is to provide a plant-level algorithm for plant owners and a scalable framework that can reduce the computational burden at the ISO level.
- Second, an inverter parameter-tuning algorithm will be discussed. The current grid can be viewed as a networked system with homogenous oscillators (synchronous generators). With more inverter-based resources entering the grid, the power system will operate in the “hybrid model” with a mix of synchronous generators and inverters. Grid-forming inverters paired with PV and storage systems could replace the frequency response provided by synchronous generators and potentially improve the system’s transient stability.
The hybrid PV plant study introduced in this talk is supported by the U.S. Department of Energy’s Office of EERE under award DE-EE0009341.
