Abstract

This paper presents a methodology for optimizing the planning and scheduling aspects of a community energy storage (CES) system in the presence of solar photovoltaic (SPV) power in low voltage (LV) distribution networks. To this end, we develop a multi-objective optimization framework that minimizes the real power loss, the energy trading cost of LV customers and the CES provider with the grid, and the investment cost for the CES. Distribution network limits including the voltage constraint are also taken into account by combining the optimization problem with a linearized power flow model. Simulations for the proposed optimization framework with real power consumption and SPV generation data of the customers, highlight both real power loss and energy trading cost with the grid are reduced compared with the case without a CES by nearly 29% and 16%, respectively. Moreover, a case study justifies our methodology is competent in attaining the three objectives better than the optimization models which optimize only the CES scheduling., Comment: 7 pages, 8 figures, 1 table, Accepted for publication at IEEE 13th International Conference on Power, Energy and Electrical Engineering

Abstract

The increasing deployment of distributed energy resources (DER) within electricity distribution systems can push them outside their safe operational limits. This urges the distribution system operators (DSO) to perform a DER capacity assessment that utilises the network’s full potential to accommodate more DER while ensuring the network’s safety. However, this is a challenging task as the DER units are mostly consumer-owned and therefore the DSO does not have control over them. To overcome this challenge, this paper first develops dynamic operating envelopes (DOEs). A DOE is a convex set defining acceptable real and reactive powers exchange with the grid at a consumer connection point without violating any network constraints. We propose a novel methodology to calculate a DOE by applying the right-hand side decomposition technique through which we allocate the network’s capacity to mutually independent consumers. We then build a hierarchical DER capacity assessment within DOEs that considers the uncertainty of solar power and demand when making investment decisions. In the proposed framework, the consumers are then free to make their decisions as long as they comply with their DOEs.
