WISPO - Wisconsin Power Systems
United States
เข้าร่วมเมื่อ 25 ก.ย. 2020
The Wisconsin Power Systems (WISPO) research group is comprised of faculty, graduate researchers and undergraduate students interested in electric power system modeling, optimization and control. We are housed in the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison.
Electricity Markets Tutorial
Introduction to electricity markets in the United States, the history, operations, and participation in those markets.
Questions:
Q: What is the revenue stream for RTOs/ISOs when they are a non-profit market operator?
A: RTOs/ISOs charge the market participants the membership fees for market access; on top of this, RTOs/ISOs provide out facing services including performing interconnection studies for developers and market training with cost to participants.

Data-driven Piecewise Linearization for Distribution Three-phase Stochastic Power Flow
Balancing Wildfire Risk and Power Outages
มุมมอง 913 ปีที่แล้ว
Electric grid faults can cause catastrophic wildfires, particularly in regions with high winds and low humidity. In real-time operations, electric utilities are left with few options for wildfire risk mitigation, leading to the use of disruptive measures such as public safety power shut-offs. This work proposes the optimal power shut-off problem, an optimization model to support short-term oper...
Linearized Three-Phase Optimal Power Flow Models for Distribution Grids with Voltage Unbalance
มุมมอง 3153 ปีที่แล้ว
Presented by: Kshitij Girigoudar Venue: IEEE Conference on Decision and Control (CDC 2021) Abstract: One of the major challenges to efficiently solving an optimal power flow (OPF) problem for large-scale, unbalanced distribution grids with high penetration of distributed energy resources is computation time. Although various convex relaxations of the OPF problems have been proposed for distribu...
Burning Issues: Modeling Risk of Wildfire Ignitions and Power Outages in the Electric Grid
มุมมอง 563 ปีที่แล้ว
Electric grid faults can be the source of catastrophic wildfires, particularly in regions with high winds and low humidity. In short-term operations, electric utilities have few options to mitigate the risk of wildfire ignitions, leading to use of disruptive measures such as proactive de-energization of equipment, frequently referred to as public safety power shut-offs. Decisions of which lines...
Control Strategies to Mitigate Voltage Unbalance using Solar PV Inverters
มุมมอง 3763 ปีที่แล้ว
Presented by: Kshitij Girigoudar Venue: INFORMS Annual Meeting 2021 Abstract: Increasing deployment of single-phase rooftop solar PV installations can lead to voltage unbalance in distribution grids. However, they are also able to minimize unbalance by providing reactive power support. We compare a centralized optimization-based strategy based on a three-phase optimal power flow formulation wit...
Comparison of Real and Synthetic Network Models of Western US with respect to New Realism Measures
มุมมอง 473 ปีที่แล้ว
Presented by: Sogol Babaeinejadsarookolaee Venue: Power and Energy Conference, April 2021 Abstract: This presentation describes results from comparison of an industry-accepted model of the western United States with two different synthetic network models of the same geographic area. The synthetic models were independently produced by different construction algorithms but based on public informa...
A Posteriori Chance Constraint Tuning for DC Optimal Power Flow
มุมมอง 493 ปีที่แล้ว
Presented by: Ashley Hou Venue: Computing in Engineering Forum at UW-Madison, September 2020 Abstract: The increased penetration of renewable energy has introduced uncertainty into power systems that can render solutions obtained from traditional, deterministic models insecure. In this poster, we present a computationally light-weight method for solving chance-constrained optimal power flow tha...
Finding Optimal Power System Frequencies
มุมมอง 303 ปีที่แล้ว
Presented by: David Sehloff Venue: Computing in Engineering (CIE) Forum 2020, Madison, USA Abstract: Developments in grid-scale power electronics have removed the necessity that power systems operate at a single fixed frequency, unlocking substantial advantages. This work quantifies these separate advantages of capacity, flexibility, and control, using a variable frequency circuit model and an ...
PowerModelsRestoration.jl: An Open-Source Framework for Power Network Restoration
มุมมอง 764 ปีที่แล้ว
Presented by: Noah Rhodes Venue: Power Systems Computation Conference 2020 Abstract: With the escalating frequency of extreme grid disturbances, such as natural disasters, comes an increasing need for efficient recovery plans. Algorithms for optimal power restoration play an important role in developing such plans, but also give rise to challenging mixed-integer nonlinear optimization problems,...
Distribution Grid Optimization: Mitigating Voltage Unbalance due to High Penetration of Solar PV
มุมมอง 2104 ปีที่แล้ว
Presented by: Kshitij Girigoudar Venue: Computing in Engineering (CIE) Forum 2020, Madison, USA Abstract: There has been growing penetration of distributed energy resources like rooftop solar PV in the recent past. The research work is focused on using optimization methods to address the power quality issue of voltage unbalance due to large-scale penetration of solar PV installations in the dis...
On the Impact of Different Voltage Unbalance Metrics in Distribution System Optimization
มุมมอง 1464 ปีที่แล้ว
Presented by: Kshitij Girigoudar Venue: Power Systems Computation Conference 2020 Abstract: Growing penetrations of single-phase, rooftop solar PV installations might lead to increase in voltage unbalance. When considering actions to reduce voltage unbalance, it is important to recognize that various organizations such as IEC, NEMA and IEEE provide different and partially inconsistent voltage u...
so I can't tell the difference between regulated markets and unregulated markets. In this system, you said ercot is the wild wild west a dozen times, but you never explained why it is the wild west, and how the better, more mature, and more sophisticated government regulators who are never bought and paid for by industry (for instance how the regulators in medical have been purchased in order to make sure insurance costs keep rising) how are regulated better than non regulated, and then you explain day ahead and 5 min, and then kind of imply that both reg and nonreg use the same system. I am so confused.
Thanks for the explanation. I am also working on Similar topic, could you provide me the material related to this topic for more detailed understanding.
