Value of hydro power plants in integrated markets for energy and ancillary services
نویسندگان
چکیده
For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New York Independent System Operator. A hydro unit with an average water availability offering its capacity in ancillary services markets in addition to energy market increases the value of existing generating capacity by 25% and nearly doubles the value of capacity upgrades.

متن کاملA new self-scheduling strategy for integrated operation of wind and pumped-storage power plants in power markets
Competitive structure of power markets causes various challenges for wind resources to participate in these markets. Indeed, production uncertainty is the main cause of their low income. Thus, they are usually supported by system operators, which is in contrast with the competitive paradigm of power markets. In this paper, a new strategy for increasing the profits of wind resources is proposed....
