“…As the West Coast grid continues to evolve, its physical and financial exposure to fluctuations in hydrometeorological conditions is likely to change as well, even without factoring in the anticipated effects of climate change. While there have been major efforts to explore power system and market dynamics under future grid configurations, including on the West Coast, few have adequately explored this system's exposure to stationary hydrometeorological uncertainty (Haas et al., 2018; Hadley & Tsvetkova, 2009; Li et al., 2016; Pereira et al., 2018). At the same time, most previous studies focused on grid impacts from hydrometeorological conditions do not consider how these sensitivities will change as the underlying technology mix evolves (Jordehi, 2018; Jurkovic et al., 2017).…”

Previous studies investigating deep decarbonization of bulk electric power systems and wholesale electricity markets have not sufficiently explored how future grid pathways could affect the grid's vulnerability to hydrometeorological uncertainty on multiple timescales. Here, we employ a grid operations model and a large synthetic weather ensemble to “stress test” a range of future grid pathways for the U.S. West Coast developed by ReEDS, a well‐known capacity planning model. Our results show that gradual changes in the underlying capacity mix from 2020 to 2050 can cause significant “re‐ranking” of weather years in terms of annual wholesale electricity prices (with “good” years becoming bad, and vice versa). Nonetheless, we find the highest and lowest ranking price years in terms of average electricity price remain mostly tied to extremes in hydropower availability (streamflow) and load (summer temperatures), with the strongest sensitivities related to drought. Seasonal dynamics seen today involving spring snowmelt and hot, dry summers remain well‐defined out to 2050. In California, future supply shortfalls in our model are concentrated in the evening and occur mostly during periods of high temperature anomalies in late summer months and in late winter; in the Pacific Northwest, supply shortfalls are much more strongly tied to negative streamflow anomalies. Under our more robust sampling of stationary hydrometeorological uncertainty, we also find that the ratio of dis‐patchable thermal (i.e., natural gas) capacity to wind and solar required to ensure grid reliability can differ significantly from values reported by ReEDS.

“…To text the practicality of an MIQP model for the UC problem with wind curtailment and pollutant emission and the effectiveness of OAM for solving the corresponding problem, some numerical simulations are performed on six systems with thermal units from 10 to 100 and one wind unit over a scheduling period of 24 h, among which the 10 thermal units parameters and load demands of each period of 10 units are taken from [18], and the harmful gas emission of thermal units parameters are taken from [19]. The 20, 40, 60, 80 and 100 thermal units data are created by duplicating the 10-unit base data.…”

Outer Approximation Method for the Unit Commitment Problem with Wind Curtailment and Pollutant Emission

This paper considers the fast and effective solving method for the unit commitment (UC) problem with wind curtailment and pollutant emission in power systems. Firstly, a suitable mixed-integer quadratic programming (MIQP) model of the corresponding UC problem is presented by some linearization techniques, which is difficult to solve directly. Then, the MIQP model is solved by the outer approximation method (OAM), which decomposes the MIQP into a mixed-integer linear programming (MILP) master problem and a nonlinear programming (NLP) subproblem for alternate iterative solving. Finally, simulation results for six systems with up to 100 thermal units and one wind unit in 24 periods are presented, which show the practicality of MIQP model and the effectiveness of OAM.

“…Also, in [8] the BESS is involved in the UC problem to improve the frequency security of the system as well as providing energy arbitrage in normal operation of the system, while it is assumed after a contingency the BESS inject all its energy to provide frequency support. In [9], a probabilistic UC model is developed by incorporating BESS and wind energy in the problem. A deterministic UC is used to co‐optimize energy storage and UC scheduling decisions for cost saving and energy arbitrage [10].…”

This paper proposes a novel energy and reserve scheduling model for power systems with high penetration of wind turbines (WTs). The objective of the proposed model is to minimize the total operation cost of the system while static and dynamic security is guaranteed by preserving the frequency nadir, RoCoF, and quasi-steady-state frequency in the predefined range. Likewise, a supervisory, control, and data acquisition (SCADA) system is developed which allows Vanadium Redox Flow Batteries (VRFBs) to continuously communicate and participate in the primary frequency response. To cope with the uncertainties, adaptive information gap decision theory is used that ensures a target operating cost for the risk-averse operator of the power system. The proposed scheduling model is applied on a modified IEEE 39 bus test system to verify the impacts of the fast reserve provided by the VRFBs in the dynamic frequency security enhancement of the power system with high penetration of WTs.
