Excessive penetration of renewable energy resources into the distribution grid without additional preventive measures has led to several operational problems. However, most strategies developed accommodate more units suffered from other Therefore, further efforts are needed address key vulnerabilities in addition maximizing hosting capacity. In this regard, study is devoted a new multi-objectiv...

Zusammenfassung In diesem Beitrag wird die beobachterbasierte Zustandsregelung von Strecken mit Stellsignalbegrenzung auf allgemeinere dynamische Ausgangsrückführungen für Zwei-Freiheitsgrade-Regelungen erweitert, die sowohl statische als auch dynamische Rückführungen beliebiger Ordnung umfassen. Die Bestimmung der neuen Ausgangsregler erfolgt durch den unabhängigen Entwurf einer statischen Aus...

Reducing carbon emissions is a crucial way to achieve the goal of green and sustainable development. To accomplish this goal, electric vehicles (EVs) are considered system-schedulable energy storage devices, suppressing negative impact randomness fluctuation renewable on system's operation. In paper, coordination control strategy aimed at minimising distribution network between EVs, static var ...

Addressing power quality issues in shipboard microgrids (SMs), which are mainly attributable to the increased installation of converters, has received much attention recently. To this end, static VAR compensators, such as thyristor-switched capacitors and fixed capacitors-thyristor controlled reactors (FCs-TCRs), can be effective solutions. Controlling these however, is not a trivial task it in...

Optimal power flow (OPF) is a crucial aspect of distribution network planning and operation. Conventional heuristic algorithms fail to meet the system requirements for speed accuracy, while linearized OPF approaches are inadequate networks with high R/X ratios. To address these issues cater multi-period scenarios, this study proposes dynamic second-order cone programming-based (SOCP) model. The...

<span>The rise in demand for electricity and the high cost of constructing new power networks reckons optimal utilization electric overloading excessive transfer along transmission lines, losses, voltage instability, poor quality, reliability issues. Flexible AC system (FACTS) boosts static dynamic performance systems. Although efficient by improving quality profile enhancement is control...

In this paper we solve the problem of static portfolio allocation based on historical Value at Risk (VaR) by using genetic algorithm (GA). VaR is a predominantly used measure of risk of extreme quantiles in modern finance. For estimation of historical static portfolio VaR, calculation of time series of portfolio returns is required. To avoid daily recalculations of proportion of capital investe...
