High level challenges that motivate the evolution towards smart grids include (i) the anticipated electrification of transportation, including electrical vehicles (EVs), and (ii) the increasing penetration of distributed renewable energy sources (DRES). This chapter will discuss how the extra grid load stemming from the EVs can be handled, including the context of reduced control over power gen...

The high variability of renewable energy resources presents significant challenges to the operation of the electric power grid. Conventional generators can be used to mitigate this variability but are costly to operate and produce carbon emissions. Energy storage provides a more environmentally friendly alternative, but is costly to deploy in large amounts. This paper studies the limits on the ...

Future grid refers to the next generation of electrical grid, which will enable smart integration conventional, renewable, and distributed power generation, energy storage, transmission distribution, demand management [...]

Colombia has prioritised the use of renewable energy to expand and improve electricity services for its population in zones non-interconnected national grid. Recent policies regulations have supported this ambition with successive measures strengthen investment conditions distributed energy, like standalone solar photovoltaic (PV) solutions hybrid PV mini-grids. Still, market is relatively imma...

Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distribute...

Turning to Renewable Energy Sources (RES) is the most logical politics in securing the modern society from critical changes in earth increasing temperature. However, Distributed Generation (DG) sources could lead to new challenges in electricity network, mainly allocation of DG sources in distribution level of power system will set the existing network under stress of power flow parameters. The...

Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...

When a city adds a renewable generation to improve its carbon footprint, this step towards a greener city can be a step towards a smarter city. Strategical positioning of new urban electricity components makes the city more resilient to electricity outages. Money and resilience are two conflicting goals in this case. In case of blackouts, renewable generation, other than distributed combustion ...

This paper describes a DC isolated network which is fed with Distributed Generation (DG) from photovoltaic (PV) renewable sources for supplying unbalanced AC loads. The battery energy storage bank has been connected to the DC network via DC/DC converter to control the voltage of the network and optimize the operation of the PV generation units. The PV arrays are connected to the DC network ...

Complex power generation scheduling, correlated uncertainties, environmental issues and hybrid energy system modeling have become very important research topics due to rapid growth of large-scale distributed renewable energy system, deregulated electric power markets and responsive demand. The intermittent nature of the primal energy sources (i.e. wind, sun, water) increases uncertainty as well...
