  • Effect of distributed generation modelling on performance of distribution systems

    Due to the continuous increase of distributed generation (DG) penetration into distribution systems, load flow analysis always needs improvement to be more flexible, fast and computationally efficient especially when integrating DG with existing distribution systems. The work in this paper is divided into two parts; in the first part a new algorithm is developed to solve the power flow problem ...

  • Assessing the benefits of a provision of system services by distributed generation

    Distributed Generation (DG) units are said to have the potential to become an integral part of the future power systems. Today, DG units are characterised by high specific investment costs, but nevertheless are politically promoted because of their high degree of energy efficiency and their capability of reducing the current dependency on fossil fuels. However, at longer term DG units have to ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Characteristics of modern nonlinear loads and their influence on systems with distributed generation

    Nonlinear electronic loads may demonstrate unexpected reactions to variations in power system voltage. This effect of the electrical load may be very significant in distributed generation power systems containing relatively small generators. This paper reviews modern nonlinear electronic load current consumption mechanisms and provides typical current waveforms. Based on extensive measurements ...

  • Programmed PWM to improve power quality in systems with distributed generation units

    Pulse-Width Modulated (PWM) inverters are widely applied in Distributed Generation (DG) units and power quality equipment owing to their excellent performance and flexible control means. Programmed PWM (PPWM), as a special type of optimal PWM strategy, theoretically allows for setting the fundamental and the selected harmonic amplitudes directly to arbitrary values. The algorithms for solving ...

  • Development and opportunities of distributed generation fuelled by renewable energy sources

    The key issue to the widespread of distributed generation (DG) is the ability to safely, reliably and economically interconnect new energy sources with the existing distribution network 'utility grid'. With the rising prices of petroleum fuel sources, a high expected penetration of renewable energy sources (RES) such as wind and solar as part of the emerging DG fuel resource are expected to be ...

  • Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system

    Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

  • A new EE resource: Distributed people

    Energy efficiency is often described as the invisible resource. It improves our energy supply without any of the usual industry trappings: smokestacks, wind turbines, transmission lines and poles. This is one of its virtues.But efficiency’s invisibility also causes problems. Because it operates out of sight – inside walls, underneath lampshades, and in factory motors — efficiency tends to attract ...

  • Wind energy generators sitting and sizing based on uncertain generation pricing

    This paper proposes a methodology for sitting and sizing wind distributed generators (WDGs). These generators are characterised by an uncertain active power production due to the random behaviour of the wind speed. The uncertain generation directly impacts the network total generation cost and also the solution for the placement and sizing problem. So, this work takes into account this uncertain ...

  • Dispachability improvement of wind generation by the Virtual Power Producers

    Today, there is a growing environmental concern about where the energy that we use comes from, bringing the attention on renewable energies. However, the use and trade of the renewable energies in the market seem to be complicated because of the lack of guarantees of generation, mainly in the wind farms. The lack of guarantees is usually addressed by using a reserve generation. The aggregation of ...
