Anomaly detection indicators of a wind turbine gearbox based on feature extraction from its vibration performance
This paper proposes a method for obtaining several health condition indicators for wind turbines based on vibration data driven from two similar experimental turbines (damaged and healthy). These indicators are able to ... -
Optimizing storage allocation and investment for transmission constrained networks considering losses and high renewable penetration
This work investigates the effects of transmission losses, constraints and increased renewable energy penetration on planning energy storage allocation and investment. By modifying a DC Optimal Power Flow model using a ... -
Analysis of storage and water value in power systems for policymaking on renewable energies
As variable Renewable Energy Source (vRES) production, e.g., solar and wind, increases, additional Energy Storage (ES) capacity may be desirable in order to manage vRES intermittency. Moreover, since Battery Energy Storage ... -
A tool for simulation, analysis and design of underfrequency load-shedding (UFLS) schemes of isolated power systems
Isolated power systems are especially sensitive to generation-load imbalances. The small size, the relatively low inertia, and the comparatively large generation in-feeds make them more vulnerable to frequency instability ... -
Reactive power capability of large hydro generators and the European grid code requirements with respect to voltage stability
IEC 60034-3 and IEEE C50.13 and C50.12 standards state that the manufacturer shall supply the reactive power capability diagram (also known as P-Q capability diagram). The reactive power capability diagram provides the ... -
White noise testing for functional time series. Application to model identification and diagnosis
White noise characterization is a crucial step in the identification and diagnosis of a model for scalar time series, where the autocorrelation and partial autocorrelation functions of the time series are the most common ... -
Joint energy and capacity equilibrium for centralized and distributed generation
This paper presents a conjectured-price-response equilibrium approach for modeling centralized and distributed generation (CG and DG respectively). The Nash game is set up with two constraints linking the CG and DG decisions ... -
A review of cross-sector decarbonisation potentials in the European energy intensive industry
The energy intensive industry (EII) is responsible for two-third of industrial carbon dioxide emissions in the EU. It has been recognised by both public and private stakeholders that a far-reaching transformation of these ... -
A framework for electricity distribution-level coordination through local flexibility mechanisms
An approach to incentivize customers to efficiently utilize existing electricity distribution networks is through dynamic network pricing. However, unintended customer responses may be obtained requiring distribution-level ... -
Combining participatory tools and multi-criteria decision methods for selecting appropriate technologies for rural electrification: an application to Rwanda.
According to several reviews, a significant part of the failure of many rural electrification programs has been due to the lack of participation of future users in the design decisions, and the overemphasis on technical ... -
An equilibrium approach for modeling centralized and distributed generation expansion planning
This paper proposes an equilibrium approach for modeling the centralized and distributed generation (CG and DG respectively) expansion planning, by representing the operation and investments decisions of both the traditional ... -
A utility approach to accelerate universal electricity access in less developed countries: a regulatory proposal
We propose a high-level definition of a large-scale business model designed to accelerate electricity access, and attract corporate investment in electrification in developing countries. The model is based on the findings ... -
Towards a more investment friendly economic incentive regime for offshore infrastructure projects
Offshore infrastructure projects will play a key role in enabling the EU to meet its renewable energy goals. Therefore, effective economic incentives must be in place to ensure adequate investments. Since the liberalisation ... -
Multi-objective bi-level optimization problem for the investment in new gas infrastructures
While there is a huge uncertainty in the gas sector and its role in the future energy mix is not clear, in order to adapt to the new challenges in the energy use, to achieve the 2020, 2030 and 2050 objectives and to continue ... -
An efficient approach to study non-perfect competition in a multi-area electricity market: application to the European case
This paper presents an efficient approach for computing medium-term market equilibrium models under non-perfect competition, with a focus on multi-area systems, with multiple market splitting options. In accordance to the ... -
Restructuring revisited: competition and coordination in electricity distribution systems
This paper addresses the implications of the emergence of distributed energy resources (DERs) for industry structure in the electric power sector. Regulations on industry structures dictate which actors can perform which ... -
Modeling unit commitment in political context: case of China’s partially restructured electricity sector
Restructuring an electricity sector entails a complex realignment of political and economic institutions, which may both delay and distort the achievement of satisfactorily competitive conditions. In research and planning ... -
An overview of natural gas network tariffs design considering the regulatory principles as guiding criteria
This paper analyses current approaches and proposals for gas network tariffs design at international level. Current challenges are examined so as to establish specific guidelines for natural gas tariff design considering ... -
De-rating of wind and solar resources in capacity mechanisms: a review of international experiences
Non-conventional renewable energy technologies are already a key element in the expansion of many power systems. These resources, whose deployment was fostered through different types of support mechanisms in the last ...
