A decision support system for hydro power plants in markets for energy and ancillary services

Abstract

This paper analyses solutions for optimal bidding for hydro units operating in simultaneous markets for energy and ancillary services and decision making process for plant refurbishment and generating capacity upgrade. Methodology based on the Decision Theory will be applied to identify the optimal solutions which minimize the expected costs and the related risks. The proposed methodology will be demonstrated for a real hydropower plant in Croatia (Varazdin HPP) which will be refurbished.

Models of Optimal Operating Modes of the Water-Economic Complex on the Basis of Hydro Resource Price Evaluation

“…Comparative analysis of the most advantageous load distribution in the power system with the representation of expressions (1) [5,[7][8][9]:…”

“…Moreover, it should be noted that since only generating sources are considered in this article, power losses in networks are neglected. Under the conditions according to the methodology from [58], the parameters b* and q* are determined by (7) and (8).…”

“…For efficient electricity generation at HPP, two main factors are necessary: a guaranteed supply of water during a year and possibly large river falls (canyon-like relief types are favorable for hydraulic construction) [3,4]. Methodologies for solving optimization problems in the case of HPP cascades are significantly complicated and not fully studied [5][6][7][8][9][10][11][12]. The reason for this was the absence in the 1970s-1980s of the necessary powerful automation tools required for solving such problems [13][14][15][16][17][18].…”
