In this paper, we formulate the distributed optimization of multi-building energy systems as a cost minimization problem with spatially and temporally coupled constraints. The problem is divided into subproblems of each building at each time slot via Lagrangian dual decomposition. The strong duality of the primal and dual problem is proved, and distributed algorithms are proposed based on the subgradient...
Under the real-time electricity pricing environment in smart grid, building owners are faced with the indoor temperature control problem to minimize the daily electricity cost. Taking the heating scenario as an example, an intuitive strategy is to maintain the building's indoor temperature always at the lower bound of the predetermined comfort range. However, this strategy may not always achieve the...
In this paper, we study the sensor selection problem for parameter estimation in wireless sensor networks (WSNs) to minimize the energy consumption with guaranteed quality of estimation. We adopt the Best Linear Unbiased Estimator (BLUE) as the fusion algorithm, and the Mean Squared Error (MSE) criterion to measure the quality of estimation. We formulate the problem as a constrained optimization problem,...
