Microgrid Controller Benefits


Use ETAP Digital Twin to design, analyze, and validate, and configure the microgrid system, objectives, and logics. Validate controller logic with ETAP software-in-the-loop (SIL) or hardware-in-the-loop (HIL) systems then simply transfer the model to ETAP Microgrid Controller to deploy.

After deployment, the controllers can control live microgrids via their communication systems and can be fine-tuned and re-deployed instantly without any decommissioning. Use the controller hardware to view, adjust parameters, set up function, update logics via easy to use HMIs that consolidates all necessary information.

Intelligent real-time situational awareness and forecast-driven predictive simulations to reliably and accurately determine short-term loading and generation, especially from inconsistent sources such as wind and solar.

ETAP Microgrid automatically identifies and adapts to system changes using proven control and optimization algorithms to handle unexpected events. Proactive generation dispatch and switching control logics regulate voltage and frequency for system preservation during and after an islanded condition.

ETAP’s Advanced Microgrid Management Control considers and responds to multiple contingencies simultaneously to preserve critical loads.

Evaluate energy-reducing strategies such as moving on-peak usage to off-peak periods or shifting from one rate schedule to another to improve the bottom line. Fast load curtailment and remedial actions based on load and generation changes and priorities.

How ETAP Microgrid Controllers manage the Red Sea Utility off-grid Microgrids in Tabuk

19:59 Webinars  
The Red Sea Utility Grid is in the Tabuk province of Saudi Arabia. The site is a vast 33,000 km2 of islands, lagoon, coastal plain and mountains with extremely diverse marine life and terrestrial landforms. The grid is divided into four off-grid microgrids. The focus of this presentation is about three of the microgrids that are very similar in size and operation. Each of these microgrids includes two PV generation (total 6 MW), two battery storages (total 5MW, ~18 MWh), and two emergency backup diesel generators (~ total 3.8 MW). The system is designed to achieve high reliability by having redundancy at various levels.

Reactive Power based LCOE Analysis

23:55 Webinars  
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.

Using ETAP to Evaluate Ground Fault Trips in a Microgrid

21:17 Webinars  
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.

Modeling and Analysis of a Microgrid for a Wastewater Treatment Plant - AECOM

16:21 Webinars  
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.

Unit Capability Validation, an Analytical Approach for MOD-25 Compliance

23:34 Webinars  
It is crucial to define the reactive power limits to evaluate the voltage support available under normal, abnormal and emergency operations with the unit's safe functioning. Published generator thermal capabilities curves, produced by the manufacturer, define the limits for safe operation based on the generator design's thermal limitations. Practically, the available reactive capability differs from the published equipment curves due to plant specific design and operating constraints. This presentation discusses a theoretical approach utilizing a simplified electrical distribution system and an ETAP model to identify and validate the plant-specific unit capability.
