Maximum feasible penetration of non-programmable RES generation in power systems
​The large-scale development of renewable sources, with particular reference to wind, in the generation mix might introduce several problems for a secure management of the power system, due to a higher generation uncertainty, thus requiring careful investigations by the responsible for planning and the involved system operators. In this context, CESI has developed a thorough […]

High RES penetration impact on Operations
​The development of Renewable Energy Sources (RES) is rapidly growing worldwide and they will play an increasingly important role in electricity power systems in the coming years. The majority of this is expected to be from Variable Non-Synchronous Renewable (VNSR) generation sources. According to the 2020 targets, significant volumes of VNSR generation are estimated across […]

International Standards provide instructions, guidelines, rules, or definitions that are then used to design, manufacture, install, test & certify, maintain, and repair devices and systems. They are essential for quality and risk management; they help researchers to understand the value of innovation and allow manufacturers to produce products of consistent quality and performance. International standards […]

Dam Safety for Hydropower Development
Hydropower projects can actively contribute to poverty reduction and life quality enhancement in local communities Hydropower is renewable because it draws its essential energy from the sun which drives the hydrologic cycle that, in turn, provides a continuous renewable supply of water. Hydropower accounts for more than 92 percent of all renewable energy generated and […]

The best network: no network
The electric power system is the most meaningful example of a “system”, made by components that are connected together to interact. In comparison with other systems, such as internet, highways, railways, natural gas infrastructures, the electric system is the most coupled one, namely any event can affect all the other elements of the network, even […]

Volatile RES & Thermal Plants flexibility
IntroductionWith the aim of reducing CO2 emissions and dependency from fossil fuels, in various countries the sharp increase of electrical RES (Renewable Energy Sources) as a result of policies of substantial subsidies is creating problems to an efficient and reliable operation of the electrical power system. Both transmission and distribution systems have to face an […]

Supergrid VS distributed generation
Super Grid, Smart Grid, Renewable Energy Sources, Distributed Generation and other fashion concepts can be astonishing when they are put together and not clearly harmonized. In fact they only apparently, but not really, imply opposite visions of the future power system. Distributed Generation (DG) has been associated, at first, with a “small scale” concept of […]
