“…It is to note the big variability in the average wind speed. Literature reports some related issues, as such: transport of excess production, electrical system fault endurance, available and flexible standby generating capacity and effective control or curtailment of wind power production (Benatia et al, 2013;Franco and Salza, 2011;Söder et al, 2007). -5.510 -5.081 -5.592 -5.743 -5.230 -5.855 -8.130 -6.507 -8.020 (p-value) (0.0 -12.141 -11.938 -10.518 -12.837 -13.498 -10.083 -8.370 -10.173 -8.135 (p-value) (0.0) (0 …”

Assessment Methodologies: energy, mobility and other real world application Autor(es):Godinho, Pedro; Dias, Joana The use of assessment methodologies is becoming increasingly important in the decision making process under very different environments. There are increasing concerns about making the best possible use of the limited available resources.There is also an increasing will of justifying the decisions in a sound way. This is even more important when considering public spending, public scrutiny and governance accountability. The use of recognized assessment techniques is actually mandatory in many situations, considering environmental, social, economic and sustainability concerns.This book gathers contributions from several authors, advancing the state-of- m e a s u r i n g T e c h n i c a l e f f i c i e n c y o f e u r o P e a n c o u n T r i e s u s i n g D aTa e n v e l o P m e n T a n a ly s i s e n e r g y e f f i c i e n c y g ov e r n a n c e i n T h e e u r o P e a n u n i o n m e m b e r s TaT e s -a n a ly s i s o n c u r r e n T s TaT We also want to thank Imprensa da Universidade de Coimbra, in particular Maria João Padez, for supporting us in the publication process.

Energy is strongly intertwined with mobility, with transportation systems accounting for a significant share of energy consumption across the world. Therefore, it is important to address energy and mobility strategies in an integrated fashion, taking into account their mutually influencing aspects. Energy and mobility strategies should contribute to sustain...

“…In particular, households cause 25% of the total green house gases emission related to fossil fuel combustion in the EU (European Environmental Agency, 2012). To mitigate their impact on both energy consumption and pollutant emissions, several technological alternatives are available in terms of energy generation systems, such as: i) an increase in the renewable energy penetration (Franco and Salza, 2011;Cozzolino et al, 2016;Lau et al, 2010); ii) distributed generation (DG) and cogeneration (CHP) or trigeneration (CHCP) (Onovwiona and Ugursal, 2006;Chicco and Mancarella, 2009;Jannelli et al, 2014a); iii) mechanical, electrical or thermal energy storage (Marano et al, 2012;Facci et al, 2014c;Jannelli et al, 2014b). Regarding DG, the definition of (Ackermann et al, 2001) should be taken as a reference, that is an electric power source connected directly to the distribution network or on the customer site of the meter.…”

The optimal design of distributed generation systems is of foremost importance to reduce fossil fuel consumption and mitigate the environmental impact of human activities in urban areas. Moreover, an efficient and integrated control strategy is needed for each of the components of a distributed generation plant, in order to reach the expected economic and environmental performances.In this paper, the transition from natural gas to electricity-based heating is evaluated for residential applications, considering the interplay between photovoltaic electricity produced on site and the thermal energy storage, to grant the optimal management of heating devices. The energy demand of an apartment building, under different climatic conditions, is taken as a reference and four power plant solutions are assessed in terms of energy cost and pollution reduction potential, compared to a baseline plant configuration. The performance of each power plant is analyzed assuming an optimized control strategy, which is determined through a graph-based methodology that was previously developed and validated by the authors. Outcomes from our study show that, if heat pumps are used instead of natural gas boilers, energy costs can be reduced up to 41%, while CO 2 emissions can be reduced up to 73%, depending on the climatic conditions.Our results provide a sound basis for considering the larger penetration of photovoltaic plants as an effective solution towards cleaner and more efficient heating technologies for civil applications. The simultaneous utilization of heat pumps (as substitutes of boilers) and photovoltaic panels yields a positive synergy that nullifies the local pollution, drastically cuts the CO 2 emission, and guarantees the economical sustainability of the investment in renewable energy sources without subsidiary mechanisms.

“…Even if wind power were predicted perfectly, variability is still a vital issue that must be considered when other generation resources are being scheduled. The non-wind generation resources, namely, controllable resources, have to be dispatched skillfully considering additional safeguards for wind power integration such as sufficient reserves, demand response, and energy storage [1,2].…”

-The probabilistic nature of renewable energy, especially wind energy, increases the needs for new forms of planning and operating with electrical power. This paper presents a novel approach for determining the short-term generation schedule for optimal operations of wind energy-integrated power systems. The proposed probabilistic security-constrained optimal power flow (P-SCOPF) considers dispatch, network, and security constraints in pre-and post-contingency states. The method considers two sources of uncertainty: power demand and wind speed. The power demand is assumed to follow a normal distribution, while the correlated wind speed is modeled by the Weibull distribution. A Monte Carlo simulation is used to choose input variables of power demand and wind speed from their probability distribution functions. Then, P-SCOPF can be applied to the input variables. This approach was tested on a modified IEEE 30-bus system with two wind farms. The results show that the proposed approach provides information on power system economics, security, and environmental parameters to enable better decision-making by system operators.
