The integration of intermittent renewable energy sources, such as solar and wind, into the existing power grid present is particularly challenging. While a portion of this electricity is used in the stand-alone applications, much of this electricity is fed into the electric power grid. Efforts are underway to identify the benefits that distributed energy resources provide to grid operation, such as loss reduction and capacity deferment. Clarkson's High Voltage Laboratory's accelerated life testing capability is used to improve grid reliability. Recent support comes from NYSERDA and GE Energy Systems to develop accelerated life assessment tools for testing reliability and life assessment of complex industrial settings. It is hoped that tools for utility designers to maximize the reliability benefits of their upgrades, help identify critical or significant design or process characteristics that require special controls to prevent or detect failure modes, will be determined.
