This document deals with the need for construction of new pumped storage hydroelectric power plants. Special attention has been dedicated mainly to the search for suitable locations to place PVEs, including utilization of new options of their placement.
The increase in variable renewable energy sources for power generation is creating a demand for more flexibility in the other parts of the value chain: networks, consumption and potentially storage facilities. Interfaces with other infrastructures may also provide flexibility. Implementation of these options for flexibility requires a more integrated approach to the regulation of the power sector...
Renewable energies cloud reduces the GHG emissions. However, renewable energies have “price gap” of electricity between renewable energy and grid power. Thus, government policies are important to lead to “grid parity.” The renewable energy policies in Japan and Europe were analyzed. As the results, I found that the policies depend on the “price gap” between renewable energy and grid power. I propose...
This paper introduces a modeling framework where a top-down integrated assessment model is soft-linked with a more detailed capacity expansion model for the European power system. This approach aims at adding regional sector specific details to results from climate change mitigation policy studies with a global scope. In particular, the goal is to analyze the cost minimizing investment plan required...
The European Union and other European countries have imposed targets to drastically reduce their emissions of greenhouse gases in the future. Those targets are from a today's perspective very ambitious making an extensive restructuring of the electric power system necessary, principally because the inclusion of renewables. Concerning this restructuration not a single but multiple paths are possible...
Europe is currently in the process of preparing a top-down methodology to support the planning of a future pan-European transmission system that potentially includes prioritised electricity highways that have the capability to address European electricity transmission and market requirements from 2020 up to 2050. In line with European directives UK is now committed to 15% of all energy coming from...
Paper focuses on regional market and signals to market participants regarding investments and risk management in cross-border electricity trading. Choice of additional criteria for optimal power system expansion depends on several indicators like number of congested hours, congestion costs, maximization of social welfare, complex and simple investment indicator, optimization of the distribution of...
In a globalizing world, dominating and the shaping energy sector can be achieved by satisfying energy quality criteria and having a structure to meet the criteria specifies international standards. Voltages, frequencies, waveforms, outages, harmonics and flicker effects are the parameter of quality criteria in a grid system. Among them, the frequency is the most important parameter in production of...
Photovoltaics are shifting from being a negligible, often ridiculed, power generation technology to a mainstream source of power. The paper recalls why photovoltaics (PV) are challenging the current method of power system planning and operations. It also reviews past research trends in PV grid integration. Three concrete concerns are discussed in detail. As a trend, the challenge for PV in power systems...
This paper analyses the application of levelized costs criterion to energy markets when there is a significant share of production from intermittent technologies in the power generation system. Under such scenario, the share of dispatchable technologies is often reduced, and producers may face difficulties to recover their production costs trough market.
In the course of its first (2005–2007) and part of its second (2008–2010) trading periods the EU ETS has revealed insufficient tightness and some inefficiencies in the allocation mechanisms used. Recent amendments to the Emissions Trading Directive will start applying after 2013, such as a reinforced EU-wide emission cap and the end of free allowances for the power sector. Even under stricter rules,...
The European Union (EU) has launched several initiatives to foster further integration between power systems of member states. In practice, integrating neighboring systems requires both infrastructures and appropriate organizations to use these infrastructures, such as cross-border congestion management mechanisms. Sometimes, these two parts are referred as the hardware and software of the integration,...
Smart grids are described as a tool to pursue a diverse set of political and environmental energy goals. Visions of smart grid implementation differ around the world, and roles in smart grids are not yet clearly defined and assigned. This paper systematically explores smart grid visions and pilot projects in selected countries representing different electricity system types: centralized versus decentralized...
This paper discusses historical and technical events in the U.S. and Europe over the last few years that are aimed at modernizing the electric power grid. The U.S. federal government has ratified the “smart grid initiative” as the official policy for modernizing the electricity grid including unprecedented provisions for timely information and control options to consumers and deployment of “smart”...
The integration of electric vehicles into distribution networks will require intelligent systems for managing the charging points and the impact on the grid. Electric vehicles represent an opportunity to manage the power demand allowing shifting the electric load to off-peak periods and to store the excess of generation from renewable generators. In addition, the electric vehicles could be used to...
The expected massive penetration of renewable energy sources (RES) in Spain, added to its limited electricity interconnection capacity, will demand not only the introduction of flexible resources in the Spanish power system but also a stronger transmission capacity between this country and Europe. In this context, this paper computes the economic additional interconnection capacity between Spain and...
Active response of electricity consumers to various conditions in the electric grid is a goal that is envisaged to be achieved within the smart grids concept. This paper attempts to summarize the knowledge obtained from analyses of the demand-side management (DSM) potential in various countries in order to identify potential benefits of introducing the DSM concept in the Czech transmission system...
In the past 10 years, very intensive integration of wind power plants (WPP) into power systems worldwide is evident. This phenomenon can have significant impacts on the normal operation of certain power systems. Especially exposed are power systems that do not possess a flexible generation portfolio, where the biggest challenge for power systems with significant amounts of installed capacity in WPP...
The paper aims at analyzing four possible development scenarios of the Italian power system up to 2050 using the multi-regional model MATISSE (TIMES based). This study has been realized for the WP2 of the European project SUSPLAN that aims to develop strategies, recommendations and benchmarks for the integration of renewable energy sources (RES) in the European context on a time horizon stretching...
We analyze the fundamental differences between locational pricing and redispatch-based congestion management, followed by an assessment of their effects on grid operation and market efficiency. It is indicated that although optimal nodal pricing and congestion redispatch can provide equal results in terms of power injections, they are not equivalent in terms of short-run social welfare. Moreover,...
