The optimal mix of distributed energy resources for a project or microgrid is dependent on many factors including project load profile, available rate structures, geographic location, space considerations, and project goals. Hourly modeling of the project over the course of a year can be used to estimate the savings and return on investment for different combinations of distributed energy resources including renewable generation, CHP generation, energy storage, and demand response. Different rate structures including time of use and real time price for electricity supply should be considered. Different operating modes for dispatching local generation assets should be evaluated including dispatching based on bulk electricity price and dispatching based on minimizing demand changes. Finally, project goals must be considered. For example, one project might prioritize maximizing renewable generation and minimizing environmental impacts. Another project might prioritize achieving full islanding capability for resiliency during grid outages.

Increasing transmission capacity is essential to meet an increased demand of electricity, integration of renewable generation and so on. The power industry’s pressing need for the most economical ways to transfer bulk power along a desired path may be met by building new transmission lines, which is a long and costly process. Alternately, it may be quicker and cheaper to increase the available transfer capacity of the existing transmission lines with a power flow controller.
Power flow control techniques have been practiced, from using inductors, capacitors, transformers and load tap changers in the earlier days of electrical engineering to power electronics-based solutions in recent years. Even though the costs and complexities of the available solutions vary widely, the basic underlying theory of power flow control is still the same as it always has been. To recommend proper solutions, SMART Power Flow Controllers are designed based on functional requirements and cost-effective solutions.
