Assessment of operation reserves in hydrothermal electric systems with high wind generation
In this paper, we propose a method to analyze the amount of operation reserves procured in a system based on two stages. The first stage is a detailed hourly unit commitment and the second stage is a simulation model with ... -
Price-maker optimal planning and operation of Distributed Energy Resources
This paper proposes a linear programming problem to find the optimal planning and operation of aggregated distributed energy resources (DER), managed by an aggregator that participates in the day-ahead wholesale electricity ... -
Incentivizig consumer response through cost-reflective distribution network charges
The emergence of distributed energy resources (DERs) provides the alternative to consumers to partially or fully self-provide electricity needs. In this context, efficient tariff design should guide efficient DERs deployment. ... -
Forecasting residual demand curves of the day-ahead electricity market with a Hilbertian ARMAX model
The offering or bidding strategy of an agent operating in a day-ahead electricity market may be optimized by modeling the competitive behavior of its competitors. This can be done using residual demand curves. For every ... -
Distribution network cost allocation using a locational and temporal cost reflective methodology
As the deployment of distributed energy resources (DERs) spread widely into distribution networks, traditional network cost allocation methodologies need to be reformed. This paper proposes a new distribution network cost ... -
Hardware-in-the-loop co-simulation of distribution grid for demand response
In modern power systems, co-simulation is proposed as an enabler for analyzing the interactions between disparate systems. This paper introduces the co-simulation platform Virtual Grid Integration Laboratory (VirGIL) ... -
The economic impact of demand response on distribution network planning
Smart meters deployment and developments in telecommunication technologies allow easier response of consumers to price signals. In this context, real time pricing together with network price signals may incentivize consumers ... -
Polymerization kinetics of acrylic bone cement: effect of two different antibiotics
In this work the influence of addition of vancomycin and cefazolin antibiotics is evaluating in relation with the polymerization kinetic. Antibiotic-loaded bone cements are widely used for primary hip arthroplasties due ... -
Two-stage recombinatory benders decomposition
The main goal of the power systems planning is the optimal management of the energy resources in order to ensure a safe and reliable operation. Otherwise, the system operation and reliability will be compromised, as happened ... -
Power-Capacity and Ramp-Capability Reserves for Wind Integration in Power-based Unit Commitment
This paper proposes a power-based network-constrained unit commitment (UC) model as an alternative to the traditional deterministic UCs to deal with wind generation uncertainty. The formulation draws a clear distinction ... -
Analysis of operation reserves in a hydrothermal electric system with high wind power share under demand and wind power uncertainties
The paper analyses the amount of operation reserves procured in a hydrothermal system to deal with wind power and demand uncertainty. The operation planning of the system is formulated as a detailed hourly unit commitment ... -
Bayesian nonparametrics for interval data. An agenda for future research
Interval analysis (IA) and symbolic data analysis (SDA) are considered in essence nonparametric. Both fields are called to play a quite relevant role in the future of Big Data (BD) or Internet of Things (IoT). In many ... -
An aggregate model of plug-in electric vehicles for primary frequency control
The penetration level of plug-in electric vehicles (PEVs) has the potential to be notably increased in the near future, and as a consequence, power systems face new challenges and opportunities. In particular, PEVs are ... -
An aggregate model of plug-in electric vehicles including distribution network characteristics for primary frequency control
In the future, the number of plug-in electric vehicles (PEVs) that will participate in the primary frequency control (PFC) is likely to increase. In our previous research, the computational complexity of the PFC problem ... -
A comparative study of techniques utilized in analysis of wind turbine data
Power produced by a wind turbine is dependent on many factors with different importance degrees. Main factors can be found by a thorough analysis of all the factors and their correlation and impact on the main output. ... -
Simulation model based on reliability and maintenance of a component and their effect on cost
Maintenance actions are important activities carried out by utilities to maintain the operability, reliability and sustainability of systems. These actions are mainly divided into two categories, corrective and preventive ... -
Transient stability enhancement of HV-ACDC grids with VSC-HVDC multi-terminal systems
Technological development in the last decade has turned renewable energy sources into real alternatives to help reduce contaminant emissions, which is an important concern all over the world. This is a challenging scenario ... -
Wind gust modeling
Overhead lines may suffer a myriad of different loads, but particularly when the stability of compact lines with pivoted insulated cross arms is studied (Paper B2-106), the wind gust modeling becomes crucial. Generally ...
