“…Some researchers have studied hierarchical DSR aggregation models for electric vehicles [75], residential loads [76], and distributed renewable energy [77]. Several studies have proposed the concept of dynamic aggregation, but most involve dynamic optimisation on a time scale [78–80] rather than hierarchical partition dynamic aggregation considering the self‐organisation and self‐coordination of aggregators and power consumers. Generally, research on load aggregation systems involves multilevel changes.…”

As a new energy‐supply service solution to address massive, distributed energy access to the power system, a virtual power plant has higher transmission reliability and real‐time communication requirements. To achieve collaborative optimisation, distributed load and energy resources must be aggregated using new information and communication technology. This study analyses underlying communication technologies for virtual power plant interaction from the perspective of standardisation, efficiency, reliability, and security, summarises the application of blockchain, cloud‐edge collaboration, machine learning, and other new information and communication technologies in virtual power plant energy trading, interaction, and scheduling, and proposes ideas for addressing shortcomings in interaction. To improve virtual power plant interaction, performance parameter mapping between communication and business technology, and multilevel virtual power plant interaction technology are proposed.

“…The application of this technology is constrained [4] because it occasionally becomes required to change grid voltage levels via converting electrical aspect. Another technique known as voltage management produces the reference reactive power over a stator voltage control circle [5], [6]. The voltage manipulate strategy (OLTCs) is restricted since there is a chance of interacting with both the utility-imposed feeder voltage control mechanism, which includes on-load tap changers [7].…”

In modern trends, the voltage profile has become increasingly critical when incorporating wind turbine energy sources because of changes in fault ride-through capabilities throughout voltage reaction. Ripple, voltage magnitude changes, and injected harmonics due to conversion switches are power quality issues for grid-integrated doubly fed induction generators (DFIG) wind sources. In this study, FACTS (flexible alternating current transmission system) devices like the static VAR compensator (SVC), thyristor controlled series compensator (TCSC), unified power flow controllers (UPFC), and static synchronous compensators (STATCOM) are used to stabilise wind energy with DFIGs. The simulation test cases using MATLAB also analyse three lines to ground fault (LLL-G) of fault measures, which showed a 9 MW that transferred to utility grid. Therefore, it is suggested to inject or absorb reactive power to stabilise the system using moth flame optimization with firebug swarm optimization (MFO-FSO). The simulation results clearly demonstrate that the proposed MFOFSO based STATCOM devices outperform the current nonlinear generalized predictive control based STATCOM, which only achieves 0.9815 per unit voltage stability, by achieving a higher voltage profile of 0.9925 per unit voltage stability with a reactive power injection of 1.82 MVAR.
