TL;DR: In this article, the impact of DR programs on the operation of the multi-microgrid (MMG) is investigated, which is executed based on a hierarchical energy management system (HiEMS) including microgrid EMSs responsible for local optimization in each MG and community EMS (C-EMS) responsible for community optimization in the MMG.
Abstract: The increased penetration of renewables is beneficial for power systems but it poses several challenges, i.e., uncertainty in power supply, power quality issues, and other technical problems. Backup generators or storage system have been proposed to solve this problem but there are limitations remaining due to high installation and maintenance cost. Furthermore, peak load is also an issue in the power distribution system. Due to the adjustable characteristics of loads, strategies on demand side such as demand response (DR) are more appropriate in order to deal with these challenges. Therefore, this paper studies how DR programs influence the operation of the multi-microgrid (MMG). The implementation is executed based on a hierarchical energy management system (HiEMS) including microgrid EMSs (MG-EMSs) responsible for local optimization in each MG and community EMS (C-EMS) responsible for community optimization in the MMG. Mixed integer linear programming (MILP)-based mathematical models are built for MMG optimal operation. Five scenarios consisting of single DR programs and DR groups are tested in an MMG test system to evaluate their impact on MMG operation. Among the five scenarios, some DR programs apply curtailing strategies, resulting in a study about the influence of base load value and curtailable load percentage on the amount of curtailed load and shifted load as well as the operation cost of the MMG. Furthermore, the impact of DR programs on the amount of external and internal trading power in the MMG is also examined. In summary, each individual DR program or group could be handy in certain situations depending on the interest of the MMG such as external trading, self-sufficiency or operation cost minimization.

TL;DR: In this paper, the authors present a set of options to promote the use of wind power in Colombia, based on simulations and modeling of the country's power sector, and extensive consultations with operators, managers, and agents.
Abstract: The purpose of this report is to provide decision makers in Colombia (and by extension other countries or regions), who are considering the deployment or consolidation of wind power, with a set of options to promote its use. The options presented are the result of an analysis of the Colombian market; this analysis included simulations and modeling of the country's power sector, and extensive consultations with operators, managers, and agents. More information on the analysis and simulations is presented in the appendixes. Wind was chosen to exemplify the range of renewable energy alternatives available to complement traditional power sector technologies on the basis of its technical maturity, its relatively low cost compared to other options, the country's experience, and its wind power potential. This report constitutes the second phase of a barrier analysis to wind energy in Colombia.

TL;DR: In this article, a probabilistic optimization model is proposed for the purpose of assigning optimal capacities to several sources of power generation, including wind power and fuel-based power, using a combination of recourse and chance-constrained approaches.
Abstract: Demand for energy is constantly rising worldwide whereas most conventional sources of energy are depleting. Environmental issues such as excessive greenhouse gas emissions impose additional constraints on the energy industry across the globe. Therefore, raising the share of clean sources of energy in power generation is of paramount importance. Wind power has specifically attracted large-scale investments in recent years since wind power is inherently ample, widely distributed and comes with minimal environmental impact. Wind, and consequently wind generated power are stochastic in nature. Therefore, wind energy is generally used in combination with fuel-based power to maintain reliability. Obviously, designing a reliable and efficient network of several power generation sources requires capacity planning. In this paper, a probabilistic optimization model is proposed for this purpose. The stochastic model uses a combination of recourse and chance-constrained approaches to assign optimal capacities to several sources of power generation including wind. Demand and wind generated power are both assumed stochastic and possibility of energy storage, importation and exportation are also considered in the network.

TL;DR: In this paper, the economic factors that drive nuclear power load-following in future European electricity systems are analyzed and a power plant dispatching model is built to simulate deregulated markets, in order to identify to what extent additional flexibility is needed from nuclear power due to more renewables.

TL;DR: Results show that in a south European city like Torino, a hybrid base station powering system allows significant cost and size reductions, with respect to the case of solar energy only (and of a diesel power generator), and roughly equals the cost of the grid-only case in 8-9 years.
Abstract: The use of solar energy to power base stations of cellular networks is becoming increasingly interesting, in both areas where the power grid is not present or not reliable, and where the power grid is ubiquitous and reliable, but energy costs keep growing In this paper, we investigate the dimensioning of the photovoltaic panel and energy storage of a hybrid base station powering system that can exploit both solar and grid energy The objective of the dimensioning is the minimization of the total capital and operational expenditures over a period of 10 years, accounting for the evolution of technology and traffic load Results show that in a south European city like Torino, a hybrid base station powering system allows significant cost and size reductions, with respect to the case of solar energy only (and of a diesel power generator), and roughly equals the cost of the grid-only case in 8–9 years When the extra energy produced by the solar panel can be sold back to the grid, the hybrid systems allow significant savings with respect to the grid-only case For the city of Aswan, with a production that is much higher than in Torino and more constant over the year, costs of pure solar and hybrid systems are significantly lower in absolute terms; hybrid systems result to be still advantageous with respect to pure solar systems
