| Summary/Abstract |
This work investigates the interaction between wind power and electricity markets. The paper is focused on balancing markets pricing policies. The proposal of a new imbalance price scheme is included and conveniently evaluated. This proposed scheme tries to minimise the use of ancillary services to compensate for deviations in searching for a more efficient market design. The effectiveness of imbalance prices as market signals is also examined, and policy recommendations regarding imbalance services are discussed. Two test cases are included that analyse the participation of a wind power producer in the Spanish electricity market using a stochastic optimisation strategy. For this purpose, the uncertainty of the variables is considered, i.e., wind power production and prediction, intraday and imbalance prices. Test cases were run with real data for 10 months, and realistic results are presented along with a hypothetical test case. The regulation of the imbalance prices may not be adequate for the Spanish electricity market because an error drop is not sufficiently encouraged. Therefore, we suggest the application of a new imbalance price scheme, which includes an additional constraint. The conclusions of this paper can be assumed to be general policy recommendations.

| Summary/Abstract |
Concentrating Solar Power (CSP) uses the solar radiation to produce electricity by means of a thermal cycle. This technology presents advantages over other renewables from the point of view of its integration into the grid and electricity markets. The reason lays mainly in its capabily of storing the received heat and producing electricity following a predetermined. This feature makes also possible its participation in reserve services, possibly increasing in this way the number of providers of this ancillary service. However, technical conditions and regulation makes this participation inefficient. In this paper, this assertion is developed and justified from estimates of the costs and benefits of this participation under the Spanish electricity market rules, as an example of the need of regulatory changes to exploit the possibilities of this new technology.
