Abstract

There are some load areas of thermal power units, around which some coal mills need frequent starting and stopping. In this paper, those areas are considered as Prohibited Operating Zones (POZs), and a new strategy is proposed to solve this issue. PPLD with POZs can be treated as a special non-convex space optimization problem and new method is needed. An improved GA-TS algorithm is proposed intend to search optimal solution. There are three major improvements on the algorithm, including application of Elite Solution List (ESL), design of solution repair strategy, and stop criterion of Tabu Search. In final part of this paper, simulation on a thermal plant with 8 units show effectiveness of the proposed strategy and improved GA-TS algorithm.
