Relay Coordination is very crucial task as it required coordination of primary and backup relays. in past various authors have proposed modification in standard overcurrent relays characteristic, modification in objective function to achieve optimum results of operating time of primary as well as backup relays. In this paper, considering normal inv...

In order to encourage the broad use of electric vehicles, lower carbon emissions, and support sustainable transportation infrastructure, electric vehicle (EV) charging stations are necessary. In this paper, a two-wheeler EV charger model is proposed based on solar PV array. Simulation of the maximum power point tracking (MPPT)-based PV array is per...

Solar photovoltaic (SPV) has become an inalienable part of the power system due to its numerous advantages over conventional energy sources. However, SPVs can be subjected to various kinds of faults which can degrade the overall performance of the system. Machine learning (ML) techniques may be useful to identify faults occurring in photovoltaic (P...

The operation of photovoltaic (PV) systems, like any other system, in fault free environment ensures maximum performance. Hence, accurate and timely fault identification of PV system demands greater importance. Present investigation proposes a stacking ensemble-based PV array fault diagnosis method, which is integrated with automatic feature engine...

Fast and reliable protection schemes, with accurate fault detection methodology, turn out to be one of the key endeavours in microgrids for improved operation and control strategies. Identification of fault at a very initial stage might result in rapid isolation, fault interruption, and reclosure of the faulty section. Reconfiguration of the networ...

An efficient optimal power flow (OPF) algorithm allows the finest setting of the plant by solving multi-objective optimization problem to minimise the overall operating cost.

DC microgrids (DCMGs) are gaining popularity mainly in shipboards and isolated power systems for their modest control and higher efficiency. However, the newer conception and less literature are forcing the operators to take up tough challenges for smoother operation of the overall system. Protection areas of DCMGs are still immature because of the...

Microgrids are becoming a prevalent part of the grid due to its’ numerous advantages on energy management system. Microgrids are perceived as the gate way for systematic inclusion of multiple renewable based distributed generations. One of the key concerns for these types of microgrids is detection of absence of the grid. This paper demonstrates a...

Appropriate placement of synchrophasor meters will save huge capital investment and give improved wide area monitoring, control, and protection. Being costly and having flexible channel capacity, the synchrophasor meters should be placed judiciously in the network to avoid unnecessary expenses. In this paper, the practical cost assessment of phasor...

Continuous monitoring is the prerequisite for secure operation and efficient control of power system. This paper presents a new and straightforward approach to monitor the system efficiently. Optimal PMU placement (OPP) deals with the complete system observability with a minimum number of PMU. The Modified Graph theoretic configuration has been pre...

Shrill power swing due to various electrical disturbances may lead to malfunctioning in distance relay and intimidating stress on the power system equipment. If fault occurs during power swing that is more dangerous and should be detected as early as possible for secure and stable operation of the power system. The power swing blocking (PSB) and de...

Small and large disturbances in power system may sometimes lead to sustained oscillation in three-phase power, often termed as ‘power swing’ in the literature. Power swing is a balanced phenomenon and may be indistinguishable from a three-phase fault. Transmission lines being protected by distance relays may be incorrectly de-energized because of a...

Faster fault detection and location has become one of the prime assignments in microgrids for better control strategies. Quick identification of fault may result in location estimation tougher due to insufficient measurement data.

Variations in impedance at the relaying point due to deviations in three phase power may lead to malfunctioning in distance relays. The relay can’t discriminate faults from swing due to symmetry in waveforms of a balanced fault and power swing. Inappropriate Power swing blocking (PSB) and de-blocking (PSD) functioning in distance relay may worsen t...
