The increasing of grid-connected variable renewable energy (VRE) on the demand side causes balance problems in power system. Thus, dealing with uncertainty, variability, and consequently, flexibility requirement is becoming an urgent challenge to system operators. Virtual plant (VPP), which bundles different types small-scale distributed resources (DERs) into a single unit for optimization will effectively mitigate those uncertainties. An optimal VPP management method proposed this article...

The benefits of small-scale renewable energy resources are restricted by a feed-in-tariff strategy that works with distribution grids only. Virtual Power Plant (VPP) aggregates diverse distributed on the demand side for efficient control, which can improve their revenue and encourage growth energy. Based general Nash bargaining theory, this paper proposes multi-VPP energy-sharing mechanism. This approach enables VPPs to increase engaging in peer-to-peer transactions. First, bargaining-based...

This article proposes a comparative study between different control strategies of wind energy conversion system. It aims to guarantee robust strategy which gives good performance despite the external disturbances. Studied system comprises turbine, permanent magnet synchronous generator, and two converters linked by DC bus. The whole is connected grid through resistor–inductor filter. A classical vector based on proportional–integral controller applied our Owing sensitivity this against...

Renewable energy sources have a variable nature and are greatly depending on weather conditions. The load is also uncertain. Hence, it necessary to use power reserve equipment compensate unforeseen imbalances between production load. However, this must be ideally minimized in order reduce the system cost with satisfying security level. quantification of could calculated through analysis forecasting uncertainty errors both generation Therefore, paper, back propagation artificial neural...

This paper presents a general operational planning framework for controllable generators, one day ahead, under uncertain re-newable energy generation. The effect of photovoltaic (PV) power generation uncertainty on operating decisions is examined by incorporating expected possible uncertainties into two-stage unit commitment optimization. objective consists in minimizing costs and/or equivalent carbon dioxide (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML"...

The purpose of this article is to provide a high performance control renewable distributed generator guarantee an electric power quality and jointly reduce the mechanical stress despite any possible uncertainties such as random nature wind speed, presence parameters uncertainties, external perturbations acting on system (sudden load variation). integrating associated with batteries module considered energy storage device variable load. proposed method designed by management supervisor...

This paper was interested in flexible control of an active generator (AG) that includes a wind turbine, battery-supercapacitors hybrid storage system, and loads. AG can operate according to grid stability islanded, synchronization, grid-connected modes. The developed strategy comprises two principal tasks: the first one is two-layer power management algorithm (PMA). response PMA enables detect islanding mode case fault monitor renewable generation into nine operating modes state-of-charge...

Due to renewable energy sources (RES) variable nature and their wide integration into power systems, setting an adequate operating reserve is important compensate unpredictable imbalance between generation consumption. However, this should be ideally minimized reduce system cost with a satisfying security level. Although many forecasting methodologies have been developed for load demand, management tools decision making of are still needed. This paper deals quantification through uncertainty...

This paper was focused on the implementation of experimental test bench for a wind power generator (WPG) connected to electrical network.

In this paper, a photovoltaic system with hybrid storage connected to the grid has been studied. A smart supervision algorithm based on fuzzy logic successfully developed. addition, comparative study of different possibilities in terms batteries longevity done using rain-flow cumulative damage method.

Accurate sizing of power reserve (PR) due to inaccurate forecast both renewable energy sources (RES) and load demand in a microgrid can provide substantial cost reductions. This paper proposes two strategies dispatch the PR into different generators. The first one uses only micro gas turbine (MGT). second MGTs plus PV based active generators (AGs). latter enables RES cover system for some period during day. To implement those methods, firstly an urban with is introduced. Then, day-ahead...
