Abstract: The integration of renewable power sources with power grids presents many challenges, such as synchronization with the grid, power quality problems and so on. The shunt active power filter (SAPF) can be a solution to address the issue while suppressing the grid-end current harmonics and distortions. Nonetheless, available SAPFs work somewhat unpredictably in practice. This is attribut...
The increasing number of electricity consumers results in power quality problems the distribution system. Solar photovoltaic integrated unified conditioner (UPQC-PV) is a widely adopted device that can improve system's voltage and current quality. This paper presents an optimal design performance analysis with double-stage solar system (UPQC-PV). A technique based on sequence component detectio...
One of the most common solutions to deal with the power quality issues of electrical railway systems is employing Railway Power Conditioner (RPC). In the conventional mode of operation, the RPC power rating deployed in every Traction Power Substation (TPS) is significantly large. This paper mainly focuses on the power rating reduction of RPC through presenting a novel combinatorial compensation...
Reduction of energy consumption and rise of cooling is a major concern in the air conditioning system especially in the area with very hot weather conditions. In hot weather conditions, the air conditioner takes more electrical power consumption to bring the comfort in specified area. In many Middle East countries, the atmospheric temperature approaches 40°C to 50°C or sometimes higher. During ...
Appropriate design and usage of Unified Power Flow Controller (UPFC), which has the ability of controlling the busbar voltage levels and transmission line power flows simultaneously, provide a suitable conditions to enhance operation of restructured power systems. In this paper, a novel control method using four degrees of freedom is represented for hysteresis based UPFC as well as a straight f...
AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption ofreactive power are further power quality problems that the supply network is encountering. In this paper, acompensation strategy with the aid of Railway Power Conditioner (RPC) is proposed to over...
This paper concentrates on compensating the power quality issues which have been increased in day-to-day life due to enormous usage of loads with electronic control. One such solution is devices like Pension Protection Fund (PPF), Active filter (APF), hybrid (HPF), etc., are used overcome Power Quality (PQ) issues. The proposed method here an active compensator called unified conditioner (UPQC)...
An intelligent control strategy is proposed in this paper which suggests the Optimum Power Quality Enhancement (OPQE) of grid-connected hybrid power systems with solar photovoltaic, wind turbines, and battery storage. Unified Conditioner Active Reactive (UPQC-PQ) designed Atom Search Optimization (ASO) based Fractional-order Proportional Integral Derivative (FOPID) controller Hybrid Renewable E...
