New Study Shows How Solar Can Improve Grid Reliability
SolarFreedomNow.com – President Obama’s publication in Science is just recent developments repetition of how far we have come with clean energy development in the last decade. The investigate now is not whether we should transition to cleaner sources of energy, but rather how do we do so in the most reliable and cost-effective space?
In California, where we are planning to satisfy at the least 50% of our electricity needs with renewables by 2030, we are working on accelerating the solutions that will enable us to integrate large quantities of clean Energy onto the grid. One of the most exciting strategies–using renewables to provide the grid reliability business traditionally provided by natural gas–just got a little closer to world.
A brand-new subject released by the California Independent System Operator (CAISO)( aka the grid motorist for most of the state) finds that large-scale solar bushes, with the right type of inverter technology, can provide many of the essential points grid reliability business the grid demands. The subject concludes that “It may in this way mitigate the impact of its variability on the grid, and contribute to important system requirements more like traditional generators.”
In a nutshell, the CAISO is saying it has acquired a strategy for operating renewables in a way that supports greater integration of renewables onto the system. Renewables can now be part of the incorporation solution.
The test was conducted in August on one of First Solar’s 300 MW PV bushes. According to the CAISO, the data expresses the capacity required of PV bushes to provide numerous grid businesses. From the report:” This data showed how the developed at advanced strength governs can leverage PV’s value from being simply an periodic Energy rich to providing services that range from rotating reservations, quantity following, voltage endorsement, ramping, frequency response, variability smoothing and frequency regulation to strength character.”
This finding is a real-world validation of studies we ended last year which found that enabling renewables to provide grid reservations, especially in the downward direction, could be a particularly useful and cost-effective space to reduce grid handling issues and greenhouse gas radiations. After all, gas bushes have to be running to provide these services, which means they are emanating carbon, and potentially gathering out renewable generation.
At the time, we publicized their respective reports the CAISO was skeptical. This pilot scheme has been very helpful to help them seriously consider renewables as part of the incorporation solution. I am beyond glad with the results and will be working with my clean Energy colleagues to identify the economic and contractual motivations that will encourage large-scale solar bushes to provide more of these grid businesses in the future. If we really want to dramatically ramping up renewables and ramping down natural gas, we will need these grid services to come from carbon-free technologies, including large-scale solar bushes.
