Let's skip the technical problems in your theory and focus on the social.
People need power to survive. You know, food, hot water, light, work, internet, mobile phones, entertainment, etc. This requires stability, not second by second pricing.
When you put a chicken in an oven, you want to cook that chicken and eat it, feed your family. Electricity price rising in the next few minutes would mean that you either have to risk disease (chicken staying in the dangerous temperatures until the electricity price drops) or being hungry and throwing food away. This is not how you want society to function.
