摘要

The increase in the installed capacities of intermittent renewable energy sources (RES), such as photovoltaic and wind power plants, imposes the need of electricity transactions between spatially distant power systems with the goal of global power balancing between production and consumption. In this paper, the methodology for determining the optimal spatial and temporal demand side management is presented, which aims to provide agreed energy transaction from one power system to another in the presence of intermittent generation from the RES and by satisfying all security constraints. The objective function of the optimization problem is the minimum total daily operating costs of conventional power plants and costs of energy losses in the transmission network. The optimal solution is calculated by using a quadratic programming method. The proposed methodology is demonstrated in the case of energy transmission through the real transmission network in Serbia. The results confirm the overall system performance improvements that include: reduction of energy losses in the system, reduction of operating costs and increase of system security.
