New York’s Reforming the Energy Vision (REV) initiative seeks to fundamentally transform the way electricity is distributed, generated and used across the State. Utilities are being challenged to adapt their business models and distribution infrastructure to meet these new goals. REV also presents an opportunity for utilities to provide their customers with a broader range of services that lead to a more diverse, innovative and resilient energy infrastructure.
A key focus of REV is the transition to local distributed energy platforms including microgrids, which can be operated in conjunction with the grid or independently in emergencies. TRC recentlypresented an educational webinar to help New York’s utilities and other decision makers take action to plan and implement successful microgrids. This presentation covers:
• Basic concepts for developing a microgrid
• Differences from operating within the conventional grid
• Preliminary engineering steps required
• Options for generation sources

The document discusses a hybrid controller for renewable energy power plants in stand-alone sites. It describes a prototype hybrid solar PV-fuel cell-battery-diesel generator system of up to 5 kW that was developed. Experimental testing showed the controller effectively switches between the different power sources based on availability and load demand. A cost-benefit analysis found the hybrid system has a payback period of 5-10 years compared to a traditional diesel-battery system due to lower operating costs and carbon tax savings over the 30-year lifetime. The technology has commercial potential for powering telecom towers, hospitals and other remote facilities independently of the grid or continuous renewable energy availability.

The document discusses improving power quality in a grid-tied photovoltaic (PV) distribution system using a hybrid control scheme and shunt active power filter. The hybrid control scheme uses FLPID, MCCF, and MSOGI-FLL algorithms to separate fundamental components from grid voltages and load currents to mitigate harmonics. It aims to destroy voltage and current harmonics in the PV system. The control scheme regulates the DC link voltage to maintain stable power transfer between the DC and AC sides under transient conditions. Simulation results show the proposed control scheme effectively improves power quality compared to other techniques.
