Abstract
The main purpose of this research paper is to investigate the long-term effects of the proposed demand-side program, and its impact on annual peak load forecasting important for strategic network planning. The program comprises a particular set of demand-side measures aimed at reducing the annual peak load. The paper also presents the program simulations for the case study of the Electricity Distribution Company of Belgrade (EDB). According to the methodology used, the first step is to determine the available controllable load of the distribution utility/area under consideration. The controllable load is presumed constant over the analyzed time horizon, and the smart grid (SG) infrastructure available. The saturation of positive effects during intense program application is also taken into account. Technical and economic input data are taken from the real projects. The conducted calculations indicate that demand-side programs can bring about the same results as the energy storage in the grids with a strong impact of distributed generation from variable renewable sources (V-RES). In conclusion, the proposed demand-side program is a good alternative to building new power facilities, which can postpone investment costs for a considerable period of time.
Highlights
The main objective of this paper is to investigate the potential effects of demand-side measures and programs on reduction of the utility peak load within the context of long-term planning
demand response (DR)/demand-side management (DSM) programs represent a worthwhile alternative to the option of building new power facilities
The case study of the entire Belgrade Utility supply area showed that the DR/DSM program proposed in this paper would be a far better option than building new power facilities, in a wide range of variations of influential parameters
Summary
The main objective of this paper is to investigate the potential effects of demand-side measures and programs on reduction of the utility peak load within the context of long-term planning To address this issue properly the smart power distribution grid with variable generation from renewable energy sources (V-RES) should be taken into consideration. Load control methods, demand response (DR) and demand-side management (DSM), are related to active (DR) and passive (DSM) participation of customers. Reference [1] investigates the potential for DSM to limit the requirement for curtailment and further facilitate the integration of renewable energy by shifting the timing of electrical demand in response to various signals including pricing and wind availability Secondary benefits such as peak-time demand reductions are considered in [1]
