Reconfiguration and self-healing method of community energy network based on unified allocation algorithm of optical storage

Abstract

The invention relates to a community energy network reconstruction and self-healing method based on an optical storage unified allocation algorithm. The method is technologically characterized by comprising the following steps of a first step, monitoring and acquiring operation state and electrical data of optical storage equipment based on a D5000 platform energy management system; a second step, according to the operation state and electrical data of the optical storage equipment acquired in the first step, determining a fault eliminating strategy and an equipment input strategy of the current community energy network and furthermore performing regrouping allocation on an optical storage equipment sequence after equipment state change, and dividing an allocation interval; and a third step, re-defining a photovoltaic power generation unit and an energy storage unit power instruction value controllable range of the allocation algorithm according to the allocation interval which is re-divided in the second step, thereby realizing allocation algorithm reconstruction of the photovoltaic power generation unit and an energy storage power generation unit, and further realizing community energy network power balance again. The community energy network reconstruction and self-healing method improves self-healing capability of the community energy network through controlling a sequence adaptive adjusting technique and an allocation algorithm adaptive reconstruction strategy.

Description

technical field [0001] The invention belongs to the technical field of power system energy dispatching, and relates to the energy dispatching of electric power systems in which the state of power equipment is uncertain and different network states coexist, in particular, a community energy network reconfiguration and self-healing method based on an optical-storage unified deployment algorithm. Background technique [0002] In recent years, the depletion of traditional energy and the huge pollution caused by the use of traditional energy have made improving energy utilization efficiency and strengthening the use of renewable energy an inevitable choice to solve the contradictions between energy demand growth and energy shortage, energy utilization and environmental protection. As one of the cleanest and most efficient ways to utilize energy, distributed power generation technology utilizes various available dispersed energy sources for power generation and energy supply, which...
