Although the installed wind generation capacity has grown remarkably over the past decades, percentage of wind energy in electricity supply portfolio is still relatively low. Due to the technical limitations of power system operations, considerable wind generation cannot integrate into the grid but gets curtailed. Among various factors, transmission congestion accounts for a significant portion of...
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...
This paper presents a novel approach for the transmission network expansion planning under generalized joint generation and transmission n-K security criteria. The proposed methodology identifies the optimal expansion plan while modeling the power system operation under both normal and contingency states. An adjustable robust optimization approach is presented to circumvent the tractability issues...
Cyber security provided by robust power systems state estimation methods is evaluated. Tools and estimators developed in robust statistics theory are exploited. The idea consists in considering redundant robust estimation techniques with different robustness properties to improve the overall detection of attacks and synthesizing a decision making process to determine whether an attack is present or...
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...
In this paper, a new coordinated control method for Battery Energy Storage Systems (BESS) to smooth long-term and short-term wind power fluctuations is proposed. Model Predictive Control (MPC) optimization is integrated with Low Pass Filter (LPF) in the proposed method. To enhance the robustness of MPC optimization, which is adversely impacted by wind power prediction errors, Taguchi's Orthogonal...
