On the economic determinants of prostitution: the marriage compensation and unilateral divorce in U.S. states
Este paper estudia el efecto de la ley de divorcio unilateral sobre la prostitución. El artículo encuentra que dicha ley reduce la prostitución. El mecanismo más plausible, tras analizar los datos, es el sugerido por la ... -
On the proper use of net present value for capacity expansion planning with renewable generation
Generation investment costs are significantly decreasing for some renewable technologies as wind or solar power, making them an attractive option for generation capacity expansion. Nevertheless, most of the available ... -
On the use of pay-as-bid auctions in California: some criticisms and alternative proposal
This document presents some ideas regarding the use of the pay-as-bid pricing rule in multi-unit auctions. In particular, we focus on electricity markets and on the proposals for adopting this kind of mechanism in the ... -
On transition from pool fires to fire whirls inside a large compartment
Atrium full-scale fire tests have been conducted under symmetric and asymmetric opening distributions with different values of inlet air velocities. Circular flow patterns are formed around the flame, inducing fire hazardous ... -
On-line evaluation and planning tool for medium voltage-broadband over power line cells
Machine-to-Machine communications networks for Smart Grids must meet specific requirements from both technical and economic perspectives. Power Line Communications are indeed winning momentum in this area because they ... -
Open phase faults in the start-up power supply system of a nuclear power generating station
This paper investigates whether existing protection schemes would detect an open phase fault in the start-up power supply system of a 1092 MW Spanish nuclear power generating station. This investigation follows to the 2012 ... -
Open versus closed loop capacity equilibria in electricity markets under perfect and oligopolistic competition - The case of asymmetric electricity generation firms
In this paper we consider cost asymmetry of generation companies when comparing open and closed loop equilibrium models of the generation capacity expansion problem in liberalized electricity markets. We show that under ... -
openTEPES: open-source transmission and generation expansion planning
The expansion of the transmission network will be a key enabler of the energy transition. However, the high level of technical detail involved in network studies meant that it was accessible only to very specialized ... -
Operation of isolated power systems under high shares of renewables
The increasing penetration of large shares of renewable energy resources allows reducing system operation costs of island power systems. However, operation of island power systems is also challenged by this increasing ... -
Optimal bidding of renewable-based VPPs in energy and ancillary service markets
The tutorial discusses the dynamic analysis and operation of virtual power plants (VPPs), that is, clusters of generators located at different locations of the grid and providing coordinated services. The tutorial is ... -
Optimal coordinated design of under-frequency load shedding and energy storage systems
Under-frequency load shedding (UFLS) is considered a fundamental protection tool against power imbalances in electrical grids, particularly in small, isolated systems. However, load shedding entails a delicate compromise ... -
Optimal coordinated design of under-frequency load shedding and energy storage systems
Under-frequency load shedding (UFLS) is considered a fundamental protection tool against power imbalances in electrical grids, particularly in small island systems. However, load shedding entails a delicate compromise ... -
Optimal demand response programs for improving the efficiency of day-ahead electricity markets using a multi attribute decision making approach
In this paper, an agent-based model is proposed to improve market efficiency by using different Demand Response Programs (DRPs) in the day-ahead electricity market. To this end, both incentive-based and price-based DRPs ... -
Optimal design of medium voltage grids of wind farms
This paper presents a method for the design of MV underground grids of wind farms. This method formulates the design problem as binary linear optimization problem implemented in MATLAB. Both investment and operation costs ... -
Optimal discretization of net head dependency in heterogeneous multi-reservoir hydroelectric systems
Modeling the net head dependency of hydro power plants constitutes a serious challenge from the optimization point of view. One possible approach is to pre-establish a discrete set of representative net heads and to formulate ... -
Optimal energy and reserve scheduling of pumped-storage power plants considering hydraulic short-circuit operation
This paper presents a mixed-integer model for the hourly energy and reserve scheduling of a price-taker and closed-loop pumped-storage hydropower plant operating in hydraulic short-circuit mode. The plant participates in ...
