Abstract:

A distributed algorithm is presented to solve the economic power dispatch with transmission line losses and generator constraints. The proposed approach is based on two consensus algorithms running in parallel. The first algorithm is a first-order consensus protocolmodified by a correction termwhich uses a local estimation of the system power mismatch to ensure the generation- demand equality. The second algorithm performs the estimation of the power mismatch in the system using a consensus strategy called consensus on the most up-to-date information. The proposed approach can handle networks of different size and topology using the information about the number of nodes which is also evaluated in a distributed fashion. Simulations performed on standard test cases demonstrate the effectiveness of the proposed approach for both small and large systems.

INTRODUCTION:

The emerging smart grid framework helps revisiting some of the fundamental challenges in power distribution systems, e.g., the economic dispatch (ED). The ED distributes the total power demand among the generating units, while minimizing the operating cost and satisfying both unitand system-level constraints [1]. Traditional optimization techniques [1] such as lambda iteration method [2], gradient method, linear programming and Newton’s method can be sensitive to starting points and could converge to a local optimum or diverge altogether [3]. Conventional approaches also include heuristic methods such as genetic algorithm [4] and particle swarm optimization [5], that can handle non-convex solution spaces and more stringent constraints. Moreover, recent advancements account for emission dispatch [6] and intermittency of renewable energy sources [7]. Despite excellent performance, majority of existing ED approaches are performed centrally.
