Tiivistelmä
Liberalization of electricity markets has resulted in a competed Nordic electricity market,
in which electricity retailers play a key role as electricity suppliers, market intermediaries,
and service providers. Although these roles may remain unchanged in the near future, the
retailers’ operation may change fundamentally as a result of the emerging smart grid
environment. Especially the increasing amount of distributed energy resources (DER),
and improving opportunities for their control, are reshaping the operating environment of
the retailers. This requires that the retailers’ operation models are developed to match the
operating environment, in which the active use of DER plays a major role.
Electricity retailers have a clientele, and they operate actively in the electricity markets,
which makes them a natural market party to offer new services for end-users aiming at an
efficient and market-based use of DER. From the retailer’s point of view, the active use
of DER can provide means to adapt the operation to meet the challenges posed by the
smart grid environment, and to pursue the ultimate objective of the retailer, which is to
maximize the profit of operation.
This doctoral dissertation introduces a methodology for the comprehensive use of DER
in an electricity retailer’s short-term profit optimization that covers operation in a variety
of marketplaces including day-ahead, intra-day, and reserve markets. The analysis results
provide data of the key profit-making opportunities and the risks associated with different
types of DER use. Therefore, the methodology may serve as an efficient tool for an
experienced operator in the planning of the optimal market-based DER use.
The key contributions of this doctoral dissertation lie in the analysis and development of
the model that allows the retailer to benefit from profit-making opportunities brought by
the use of DER in different marketplaces, but also to manage the major risks involved in
the active use of DER. In addition, the dissertation introduces an analysis of the economic
potential of DER control actions in different marketplaces including the day-ahead Elspot
market, balancing power market, and the hourly market of Frequency Containment
Reserve for Disturbances (FCR-D).
