Pricing electricity in constrained networks dominated by stochastic renewable generation and electric energy storage

نویسندگان

چکیده

This paper studies the electricity price formation in a competitive market when introducing generation from variable renewable energy technologies with zero marginal cost and electric storage systems. A power system is analyzed stochastic optimization model combining multi-period optimal flow dynamic programming. The results illustrate how energy, this case solar photo-voltaic generation, displaces some of expensive thermal reduces price. Electric will reduce variations caused by demand as time cap reduced. In systems only storage, be set probability scarcity similar to hydro dominated indicated future expectation value. assumes that inflexible. However, resulting prices remunerate provision flexibility, which turn contribute securing supply reducing volatility.
