Konexa rolling out its integrated distribution model with multiple DISCOs across Nigeria. In its sub-concession area, Konexa will develop embedded generation capacity (solar PV), and invest in the distribution network (medium voltage line, distribution transformers, injection substations) and last mile reticulation (low voltage lines, smart metering infrastructure). In addition, Konexa will invest in and implement IT & OT systems and processes to drive operational efficiency and significantly reduce ATC&C losses. The first phase of the project would serve about 7,000 customers (C&I and residentials).
This presentation defines and demonstrates the importance of remote data collection of protection relays for the security and reliability of large power system networks.
High penetration of solar PV energy fed into an electrical grid brings its share of challenges making the grid volatile which requires stabilizing variable energy. This presentation addresses one such challenge, of voltage profile improvement with reactive power compensation at the point of interconnection. A solar PV plant is rated in terms of power (either AC or DC) and is typically not rated for their reactive counterparts (MVAr). IEEE 1547/UL 1741 compliant inverters will typically not have reactive power capability and operate with a unity power factor. Although modern inverters have a capacity to supply reactive power in the range of +0.9 lead/-0.9 lag, the PV plant is rated based on the AC power supplied by the inverter at unity PF. Operational data sourced from various plants in India suggest that a typical utility-scale PV plant provides reactive energy in the range of 7% to 10%. This leads to an inherent error in the per-unit cost calculation, as when the inverter providing the reactive power, the active power is hampered. This paper showcases a cost-to-benefit analysis of various scenarios, such as unity power.
Adding distributed generation sources to existing power distribution systems and the implementation of islanding microgrid capability introduce protection and control challenges if not properly designed. Each new generator may present a new source ground fault current to the system, which can result in unanticipated breaker operation. Energy Systems Group, was using ETAP to model the system and check coordination of local and remote breakers can reduce downtime and troubleshooting.
For some types of generator exciter systems, collector rings and brushes are used to provide energy from the exciter to the rotating field. The brushes wear down and constantly need to be replaced with the unit on-line and while brush/ring assembly is still energized, a risky and unsafe maintenance operation and may cause a serious harm. A potential shock and arc-flash hazard. This presentation addresses the important and dangerous maintenance of worn-down collector rings and brushes, electrical safety, lack of standards and guidelines, and a first possible calculation method.
This presentation will address the difficulties and lessons learnt on performing arc flash analysis using available methods (outside the voltage limits of IEEE 1584-2018 standard) on a 2.3 MW PV generation facility. The analysis includes system modeling, short-circuit, arc flash (both AC and DC) using various applicable calculation methods that best fit this application along with available tools in ETAP and generating worst-case arc flash deliverables.
Une analyse des risques d’arc électrique AC a été réalisée sur un nouveau centre de données en Italie afin de calculer l’énergie incidente et les distances limites d’arc électrique à différents points de l’installation, depuis les cellules de distribution principale 15 kV jusqu’aux tableaux généraux basse tension et aux tableaux de distribution de chaque zone.

Engineering and operation objectives of mission-critical facilities require a reliable and secure power supply system. Microgrids have become the leading technological solution for a resilient and sustainable supply of electricity for critical infrastructures. This paper presents ETAP-based power system studies of a microgrid designed for a mission-critical facility, a wastewater treatment plant (WWTP). The microgrid consists of a behind-the-meter (BTM) solar photovoltaic (PV) system, a battery energy storage system (BESS), a combined heat and power (CHP) generator, and standby diesel generators. We modeled this microgrid by leveraging the ETAP software and performed power system studies for both grid-connected and islanded modes of operation. Several scenarios were created based on different loading conditions and power source combinations, which are utilized to validate the power system studies. We will discuss the model of the power system investigated, operational strategy and sequences of operation, findings, challenges, lessons learned, and future works.
