The concept of virtual power plant (VPP) has been proposed to facilitate the integration of distributed renewable energy. VPP behaves similar to a single entity that aggregates a collection of distributed energy resources (DERs) such as distributed generators, storage devices, flexible loads, etc., so that the aggregated power outputs can be flexibly dispatched and traded in electricity markets...

Distributed Energy Resources (DER) are systems that produce electrical power at the site where the power is needed. If only electrical power is used then the technology is called Distributed Generation (DG). The objective of this paper is to study a novel more than five level multistring inverter topology for DERs based DC/AC conversion system. The distributed energy resource based single-phase...

Rapid renewable energy sources (RESs) deployments in transmission and distribution networks have changed power systems’ operation control mechanisms. This fundamental shift makes the interaction between systems more sensitive requires robust TSO–DSO coordination to ensure system stability ancillary services for entire network. paper uses an electromagnetic transient (EMT) simulation tool using ...

In general, a large percentage of the electric power produced is generated in huge generation centres far from the consumption, and with centralized transmission and distribution systems, where the weak point of this scheme is the efficiency with high energy losses in the form of heat. This problem has been increased in the last years due to the significant growth of electric energy demand and ...

Real-time state estimation using a digital twin can overcome the lack of in-field measurements inside an electric feeder to optimize grid services provided by distributed energy resources (DERs). Optimal reactive power control DERs be used mitigate distribution system voltage violations caused increased penetrations photovoltaic (PV) systems. In this work, new technology called Programmable Dis...

The growing penetration of distributed energy resources (DERs) in urban areas raises multiple reliability issues. The topology reconstruction is a critical step to ensure the robustness of distribution grid operation. However, the bus connectivity and network topology reconstruction are hard in distribution grids. The reasons are that 1) the branches are challenging and expensive to monitor due...

As the penetration of non-dispatchable renewable energy increases around the world, there is greater need to have smart power electronics interfaces to stabilize the electricity grid. Distributed Energy Resources (DERs) with advanced grid functionality and utility communication capabilities have the ability to assist grid operators with frequency and voltage regulation. As a result, the Califor...

Future power systems with a high share of intermittent renewable energy sources (RES) in the portfolio will have an increasing need for active balancing. The integration controllable and more flexible distributed resources (DERs) at distribution-grid level represents new solution sustainable alternative to conventional generation units providing balancing services transmission system operator (...

In a technically advanced world where demand is increasing very fast especially large number of non-linear loads and electric vehicles has led to energy crisis pollution grid power. Depleting conventional sources environmental concerns integration distributed resources (DERs) at distributional level resolve problem reduce emissions. With connected different types DERs, it challenging manage the...

The increasing penetration level of distributed energy resources (DERs) increases the risk congestion in distribution network. To mitigate this, concept small-scale DER aggregator was introduced as a change from uncoordinated to coordinated DERs. However, without appropriate network use cost allocation, unwanted curtailment will be enforced by operator. Therefore, this paper proposes new approa...
