As a result, it may require that network planners make a significant amount of investments in the electricity grids over the coming decades so as to allow the accommodation of these new flows in a way that both the thermal and voltage network constraints are respected. These investments may include a portfolio of infrastructure assets consisting of traditional technologies and smart grid technologies. One associated key challenge is the presence of uncertainty around the location, the timing, and the amount of new demand or generation connections. This uncertainty unavoidably introduces risk into the investment decision-making process as it may lead to inefficient investments and inevitably give rise to excessive investment costs. Smart grid technologies have properties that enable them to be regarded as investment options, which can allow network planners to hedge against the aforementioned unc...

Articles 9 and 10 of the RES Directive regulate the implementation of joint projects between one or more European Member States and one or more third countries in order to enhance the cross border exchange of renewable energy. Besides their high solar potential, only few MWp of PV have been installed until today in MENA countries. Even though the RES Directive provides the European Member States with clear guidelines on how to implement the cross border exchange of renewable energy, until now the European Members States have not implemented the flexible mechanisms to exchange renewable energy among European Member States and third countries. In order to unblock this situation and to reach a cross border exchange of renewable energy, European Member States have to be provided with additional tools and information on the relevance of PV electricity imports from MENA countries. The PV Parity project aims at defining an appropriate policy and legal framework to improve the PV electricity imports from MENA countries. This will be done by: definition of the competitiveness of PV electricity import from MENA countries overview of the situation in the MENA countries cost analysis of the investments needed for the PV electricity imports from MENA countries market frameworks for the cross border exchange of electricity between Member States and MENA countries roadmaps towards the competitiveness of PV electricity import from MENA countries proposal for an incentive schemes for MENA countries policy recommendation to National and European policy makers for a sustainable growth of PV This paper provides an overview of the results achieved until now within the PV parity project, which are: • definition of the competitiveness of PV electricity import from MENA countries • overview of the situa [...]

The studies address concerns about the impact of wind power’s variability and uncertainty on power system reliability and costs as well as grid reinforcement needs. Quantifiable results are presented as summary graphs: results as a MWincrease in reserve requirements, or €/MWh increase in balancing costs, or results for capacity value of wind power. Other results are briefly summarised, together with existing experience on the issues. There is already significant experience in integrating wind power in power systems. The mitigation of wind power impacts include more flexible operational methods, incentivising flexibility in other generating plants, increasing interconnection to neighbouring regions, and application of demand-side flexibility. Electricity storage is still not as cost effective in larger power systems as other means of flexibility, but is already seeing initial applications in places wi...

PV was the 1st source of electricity installed in Europe in 2011, with 21.6 GWp of new power generation capacity. As comparison to other technologies, during the same period of time there were only new capacity of 9.6 GW for wind power plants, 9.7 GW for gas power plants, 2.1 GW for coal power plants, 0.6 GW for large hydro power plants and a decommissioning of 1.1 GW of fuel oil power plants and 6,2 GW of nuclear power plants. Based on these figures, PV has been seen as a potential and feasible electricity source in Europe. In the upcoming years the installed capacity of PV has to further increase to reach the "20-20-20" binding targets of 20% of RES in energy consumption until 2020, which corresponds to 30-35% of the electricity demand from RES, according the Renewable Energy Directive (2009/28/EC) and beyond, until 2050, to achieve the targets of the Energy Roadmap 2050. According to the High RES scenario of the Energy Roadmap 2050, the share of RES in electricity should reach 75% in gross final energy consumption and 97% in terms of electricity production. Among the other renewable power technologies, PV will provide a relevant contribution to reach these ambitious European targets. To achieve such contribution from RES electricity, several key challenges need to be further addressed. At the time being, the status quo in the field of electricity generation is still based on a centralized concept, where electricity producers from small-scale renewable energy systems, such as photovoltaic systems, are forced to adapt their needs, in terms of legal and regulatory framework, grid access and market design rules, to the infrastructures developed to support a centralized approach for electricity production. The PV parity project aims at defining an appropriate policy and legal framework to ensure a sustainable PV market growth. To reach this ambitious target, during the PV Parity project, European and National p [...]

This integration maximises the synergy across different energy sectors to improve the value and utilisation of investment, especially in low-carbon technologies across all sectors. This study presents an integrated multi-energy optimisation model to evaluate the economic performance and system implications of different road-transport decarbonisation strategies and analyse the synergy with the power sector decarbonisation. The large-scale optimisation model is formulated to consider the interactions across electricity, hydrogen, and transport sectors and used to determine the optimal solutions for investment and sector-coupling operation in the system. The proposed model is tested using a range of transport decarbonisation scenarios considering the deployment of electric or hydrogen vehicles or their combination and the integration with the power system. The studies analyse the economic performance and optimal energy system portfolios across different scenarios. The results demonstrate the importance of road-transport and power-to-gas integration in Great Britain's future energy system.
