For a successful rollout of electric vehicles (EVs), it is required to establish an adequate charging infrastructure. The adequate access to such infrastructure would help to mitigate concerns associated with limited EV range and long charging times. Battery swapping stations are poised as effective means of eliminating the long waiting times associated with charging the EV batteries. These stations...
Power systems around the world have set ambitious targets for renewable energy integration. Several jurisdictions incentivize renewables such as the Feed-in Tariff in Ontario, Canada. These incentives shall eventually run out and renewables would have to competitively sell energy into electricity markets, overcoming uncertainty and variability in their output. This paper proposes a Wind Generators...
Demand response aims at utilizing flexible loads to operate power systems in an economically efficient way. A fundamental question in demand response is how to conduct a baseline estimation to deal with increasing uncertainties in power systems. Unfortunately, traditional baseline estimation lacks the ability to characterize uncertainties due to their deterministic modeling. This deficiency often...
With high penetration of renewable generation, power system operations need additional ramping capability to follow the change of renewable generation. However, without proper unit commitment in the forward energy scheduling process, the system may not have sufficient ramping capability in the real time operation when renewable generation varies while system load is sharply pulling up or ramping down...
With increasing renewable energy resources, price-sensitive loads, and electric-vehicle charging stations in the power grid, uncertainties on both power generation and consumption sides become critical factors in Security-Constrained Unit Commitment (SCUC) problem. Recently, min-max robust optimization approaches are employed to solve SCUC problem. A novel robust SCUC approach is proposed in this...
As the level of renewable generation on the power system increases, so too does the uncertainty and variability it introduces. It may no longer be appropriate to schedule units at an hourly resolution as the system's sub-hourly variability and uncertainty may be underestimated. This paper examines if a sub-hourly unit commitment model is applicable for systems with high variability compared to the...
This paper presents an integrated expansion planning model of electric and natural gas distribution networks that plan both networks as one system. The model also considers demand uncertainty of power and natural gas consumption. An integrated model is more convenient for utilities that provide both services since economies of scope can be realized. Additionally, demand uncertainty provides a more...
