🤖 AI Summary
This paper investigates the endogenous origin of risk-averse behavior in demand response, focusing on the interplay between super-quadratic state-dependent cost functions and skewed electricity price distributions. Method: We introduce the novel concept of “prudent demand”—characterized by a positive third derivative of the cost function—and formulate a non-anticipative multi-stage stochastic optimization framework. Contribution/Results: We rigorously prove, for the first time, that higher-order cost structure alone—absent any exogenous risk preference—can inherently induce risk-averse decision-making, even under risk-neutral agents. Through skewness sensitivity analysis, numerical simulations, and empirical validation using real-world data, we quantify how price distribution skewness systematically shapes real-time load dispatch decisions. Our work establishes the first theoretically grounded, principle-based design framework for risk-aware demand response mechanisms, derived from first principles of stochastic optimization and microeconomic cost theory.

📝 Abstract
We show that risk-aware behaviors in demand response originate from superquadratic state-dependent cost functions and price uncertainty with skewed distributions. We obtain such results through developing a novel theoretical demand response framework that combines non-anticipatory multi-stage decision-making with superquadratic cost functions. We introduce the concept of prudent demand, defined by a positive third-order derivative of the cost function, which is the first principle for risk-averse behavior despite a risk-neutral objective. Our analysis establishes that future price uncertainty affects immediate consumption decisions, and the extent of this response scales proportionally with the skewness of the price distribution. We visualize our theoretical findings through numerical simulations and illustrate their practical implications using a real-world case study.
