Reactive Power based LCOE Analysis

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

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.

Microgrid Design & Analysis

Microgrid Analysis & Design is an essential step for Microgrid Implementation. Upfront design and analysis of the target microgrid system, whether for brownfield or green-field Microgrid implementation, can help drive both technical and financial benefits, including determining optimized generation assets required to meet the microgrid objectives as well as a projection of return on investments. Analysis & design from safety, reliability, and financial perspective are critical for successful microgrid implementation to minimize the impact and rework during the installation phase. This presentation will provide recommendations on best practices for Microgrid Analysis & Design.
