Additional applications of demand side management techniques in power systems integrated with distributed generation

Demand side management is a technique used to control customers´ loads in stand-alone power systems in order to maintain a balance between generation and electricity demand of those systems [1]. By maintaining this balance, demand side management can maintain the stability of those power systems, hence reducing the number of power interruptions to customers. It is also used in grid-connected power systems in order to reduce peak demands [2, 3, 4], hence protecting the systems from overloading. An investigation was carried out to identify further roles that demand side management can play in the integration of distributed generation in grid-connected power systems. Four potential roles were identified. 1. Solving voltage rise problems at power systems integrated with a large number of renewable generators 2. Minimising the export of renewable power to the grid for small generating plants 3. Minimising discrepancies between actual and contractual demand volumes under NETA 4. As a tool for electricity service companies (ESCOs) responsible for electricity generation and supply This paper discusses the details of two identified roles: voltage rise and export minimisation.
