Abstract

This paper analyses the phenomenon of immigration from the point of view of political and social actors. It particularly deals with the role the political parties and the parliamentary groups play in the defense and criticism of the migration policies that are applied. To reach this aim, a brief diagnosis of the recent immigration history in our country and the legislative policies has been carried out. This has been followed by an analysis of the electoral program of the four national parties, with the aim to show if the politicization of immigration and the citizens´ view over the same subject acquires its references in the mentioned programs or on the contrary it is guided daily by the parliamentary groups and means of communication.

Abstract

Article number 4402 Concentrated solar power (CSP) and photovoltaic (PV) solar systems can be hybridized, creating synergies: on one hand procuring dispatchability by storing thermal energy, and on the other hand generating electricity at a highly competitive prize. In this paper, we present an approach to the operation strategies and modes for integrated hybrid CSP + PV systems. We focus on parabolic trough (PT) solar plants, especially those operating in the south of Spain. Our study consists in the definition of suitable states for each of the subsystems that constitute a hybrid solar plant. We then propose modes from the combination of suitable states and establish the conditions for the transition between modes depending on the operation strategy. We propose two operation strategies: demand coverage and base load production. The results of this paper can be used in decision making for hybrid solar system simulation programs.
