Power purchasers now demand that renewable generators, namely wind and solar, mimic traditional fossil-fuel generation by requesting them to provide smoother power, dynamic VAR compensation, and firm day-ahead schedules, among other things. Xtreme Power® enables an inherently variable resource to meet these standards with a single superior and cost effective solution: the Dynamic Power Resource® (DPR®). Wind and Solar Renewable Independent Power Producers (IPPs) gain considerable value from the DPR, whether it be from higher Power Purchase Agreement prices for firmer power, having the opportunity to participate in lucrative Ancillary Services Markets, taking advantage of energy arbitrage opportunities, a reduction of balancing costs, or a combination of services.
The main services for Renewable Integration are:
Ramp Control and Smoothing
The DPR monitors output from the generation source on a microsecond basis and automatically responds by either absorbing generator output or supplying DPR output so that the grid receives smooth, clean power at a desired MW/minute rate.
The unique sizing scheme of the DPR allows the customer to add more energy storage (MWh) and act as a responsive supply resource for prolonged periods of time via Automatic Generation Control (AGC). In doing so, not only will a greater amount of renewable energy be delivered to the grid, but emissions from fossil generation will be reduced.
Frequency Response (Primary Control)
Like generator droop response and turbine-generator rotating inertia, the DPR can actively correct frequency deviations automatically in real time with power injections and withdraws following major electrical disturbances, as well as address less severe frequency deviations due to normal grid operations throughout the course of each day.
Coupling a DPR with a renewable generation forecast allows the customer to organize other generation resources to meet expected demand based on its guaranteed day-ahead output schedules, as well as reshape output to deliver power during peak demand times regardless if the renewable asset is generating power or not. If a forecast is inaccurate, the DPR automatically supplies or absorbs power on a microsecond basis to ensure the day-ahead output schedule is met.
If there are times when the utility needs to curtail renewable output, the DPR can take advantage of nature’s as-available, clean fuel by storing curtailed energy and redistributing it at other times.
