Abstract

Disclosed is an investment planning method and device based on power grid resources. The method includes the steps of screening, according to a comprehensive evaluation index system of a power grid communication resource construction project, investment projects to obtain power grid communication resource construction projects satisfying the condition; building an additive effect function P<a<ij>> according to relationships between projects, wherein the relationships between the projects are of a complementary type, a mutually exclusive type, a subordinate type, and other types; based on the modern portfolio theory, obtaining a technical benefit Ti of each project according to a bandwidth occupancy rate and a core utilization rate, and obtaining a reliability benefit Bi of each project according to a reliability index; according to the relationships between the projects of the additive effect function P<a<ij>>, the technical benefits Ti and the reliability benefits Bi, obtaining a power grid resource investment objective function J; and according to a constraint relationship between the projects and capital, solving the power grid resource investment objective function J by using a genetic algorithm, and obtaining a power grid investment project. According to the embodiment of the invention, the overall project investment income is improved.

Description

technical field [0001] The invention relates to the technical field of grid resource combination, in particular to an investment planning method and system based on grid resources. Background technique [0002] Power grid communication resource investment planning is the pre-planning of the optimal combination of future communication resource construction projects. Its purpose is to consider the constraints of existing investment funds, rationally allocate the investment and construction funds of grid communication resources, so as to achieve the optimal investment portfolio in the candidate projects, and then create the optimal investment benefits. The significance of studying the grid communication resource investment planning model is to realize the optimal budget of grid communication resource investment, realize the optimal combination of grid communication resource construction projects, realize the maximum benefit of grid communication resource investment, and realize...
