“…Thus, regulating the generated voltage and harmonic compensation of nonlinear loads connected to it remain the two major concerns for SEIG‐based biofuel generation system. Both passive as well as active elements can control the generator voltage in SEIG. Owing to its superior dynamic performance, ability to supply the variable reactive power needed with varying loads, elimination of current harmonics, and imbalance caused by nonlinear power electronic loads, static synchronous compensators (STATCOMs) offer the appropriate scheme for voltage control.…”

Summary Medium voltage direct current (MVDC) is an emerging trend in ship power system to cater the growing power demand in modern navy applications. Marine diesel oil (MDO) is the primary fuel in the shipping sector. However, with rising oil prices and harmful emissions, there is a greater need than ever for ship operators to consider clean power generating options. Keeping this in mind, this paper aims to present a renewable energy solution through development and integration of a three‐phase self‐excited induction generator (SEIG)–based renewable biofuel generator in MVDC ship power system. A three‐phase current controlled voltage source inverter (VSI) working as a static synchronous compensator (STATCOM) performs multiple tasks of harmonic elimination and regulation of the generated voltage under varying load. Gating pulses to the STATCOM switches are generated using indirect current theory‐based controller. An integral sliding mode‐controlled direct current to direct current (DC‐DC) converter feeding ship service loads in MVDC shipboard system has taken as a nonlinear load. A laboratory prototype of the complete system has developed to validate the concept.

This paper offers an alternative technique, namely, Improved Electronic Load Controller (IELC), which is proposal to improve power quality, maintaining voltage at frequency desired level for rural electrification. The design and development of IELC are considered as microhydroenergy system. The proposed work aims to concentrate on the new schemes for rural electrification with the help of different kinds of hybrid energy systems. The objective of the proposed scheme is to maintain the speed of generation against fluctuating rural demand. The Electronic Load Controller (ELC) is used to connect and disconnect the dump load during the operation of the system, and which absorbs the load when consumer are not in active will enhance the lifestyle of the rural population and improve the living standards. Hydroelectricity is a promising option for electrification of remote villages in India. The conventional methods are not suitable to act as standalone system. Hence, the designing of a proper ELC is essential. The improved electronic load control performance tested with simulation at validated through hardware setup.

“…The second area is the selection of the capacitance required for self-excitation and build up of the machine terminal voltage. This has been addressed for two different topologies; a fixed capacitor connected in shunt or in series with the machine stator winding [8][9][10] or a reactive power compensator connected across the machine terminals [11,12]. The reactive power is controlled to support the machine terminal voltage against load variations.…”

Incentives, such as the Feed-in-tariff are expected to lead to continuous increase in the deployment of Small Scale Embedded Generation (SSEG) in the distribution network. Self-Excited Induction Generators (SEIG) represent a significant segment of potential SSEG. The quality of SEIG output voltage magnitude and frequency is investigated in this paper to support the SEIG operation for different network operating conditions. The dynamic behaviour of the SEIG resulting from disconnection, reconnection from/to the grid and potential operation in islanding mode is studied in detail. The local load and reactive power supply are the key factors that determine the SEIG performance, as they have significant influence on the voltage and frequency change after disconnection from the grid. Hence, the aim of this work is to identify the optimum combination of the reactive power supply (essential for self excitation of the SEIG) and the active load (essential for balancing power generation and demand). This is required in order to support the SEIG operation after disconnection from the grid, during islanding and reconnection to the grid. The results show that the generator voltage and speed (frequency) can be controlled and maintained within the statuary limits. This will enable safe disconnection and reconnection of the SEIG from/to the grid and makes it easier to operate in islanding mode.
