The invention discloses a method and a
system for
power grid resource configuration, and an input-and-output metering method and
system for
power grid resource configuration. The
power grid resource configuration method comprises steps that a first power supply party
deviation function is constructed according to a power supply party plan,actual
generating capacity and the first preset unit data; a first default function is constructed according to a first preset
default rate; a contract input metering function of each contract of a power supply party is constructed according to a second default determination result of the power supply party, a preset contract value of each contract, a guarantee fund rate and a second
default rate; a main power supply party input metering function is constructed according to the functions of the previous steps; a second
electricity user party
deviation function is constructed, and a main
electricity user party output metering function is constructed according to a preset contract value of each contract of an
electricity user party; the main power supply party input metering function and the main electricity user party output metering function are written into an
electric power resource configuration model, and optimal configuration parameters are acquired for configuring
electric power resources of the power supply party and the electricity user party. The method is advantaged in that the
electric power resources of the power supply party and the electricity user party are reasonably configured, and development demands of the
electric power industry are satisfied.
