How Much Could South Asia Benefit from Regional Electricity Cooperation and Trade?
Demand for electricity in South Asia has been growing at annual rates close to 5% over the last decades supported by a sustained increase in access rates and in economic development. Currently, national power systems are operated and developed relatively independently, however, the modeling results indicate that the regional electricity cooperation and trade could reduce total undiscounted electricity supply costs in the region by US$222 billion, or more than US$9 billion per year until 2040.
Iberian electricity Iberian electricity system in the face of an increase in wind power generation
The study of wind power has high relevance in the Iberian Peninsula due to its limited interconnection capacity. The present article presents a study about the impact of wind power in the electrical grid
Large scale renewable power integration with electric vehicles
A transition from a fossil fuel based mobility to one based on electricity from renewable sources can allow for significant greenhouse gas reductions as well as of air pollutants and noise in urban areas. In addition, greater independence from imported oil in the transport sector can be achieved. One major advantage of electric vehicles is the high flexibility in charging times, which can be used to integrate renewable power generation and to make the operation of the system more efficient. The modelling exercise performed proves not only the feasibility of a power system with a RES share of over 85% assuming an ambitious network expansion, but also that electric vehicles can integrate the renewable power generation required for decarbonizing the transport sector.
The German government’s plans for the energy transition provide a long-term roadmap for the transformation of the energy supply in Germany. The challenges associated are considerable and not yet fully understood. This study presents the results of several investigations of the transformation considering electricity, heat and fossil fuels, clearly outlining the development scenarios for each, including dynamic simulations across Europe for validation considering the role of load balancing, network expansion, demand response and electricity storage among others.
The report evaluates up to 2050 the prospects of electromobility in a supply system with a high share of renewables. For this, several scenarios were assessed to identify the prerequisites for successful market development. Additionally, dynamic simulations of power system operation were carried out. The analyses show the potential of controlled charging of vehicle batteries for electricity balancing as well as, the feasibility of grid integration of electromobility and synergy effects with decentralized power generators at distribution level.
